Don’t miss this second chance at a potentially lucrative opportunity
Ever feel like you missed the boat in buying the most successful stocks? Then you’ll want to hear this.
On rare occasions, our expert team of analysts issues a “Double Down” stock recommendation for companies that they think are about to pop. If you’re worried you’ve already missed your chance to invest, now is the best time to buy before it’s too late. And the numbers speak for themselves:
- Amazon: if you invested $1,000 when we doubled down in 2010, you’d have $20,803!*
- Apple: if you invested $1,000 when we doubled down in 2008, you’d have $43,654!*
- Netflix: if you invested $1,000 when we doubled down in 2004, you’d have $404,086!*
Right now, we’re issuing “Double Down” alerts for three incredible companies, and there may not be another chance like this anytime soon.
*Stock Advisor returns as of October 21, 2024
With that, I will now turn the call over to David for introductory remarks.
David V. Goeckeler -- Chief Executive Officer
Thanks, Peter. Good afternoon, everyone, and thank you for joining the call to discuss our first quarter fiscal year 2025 performance. Western Digital delivered revenue of $4.1 billion, non-GAAP gross margin of 38.5%, and non-GAAP earnings per share of $1.78. Our dedication to lasting quality and reliability through our industry-leading innovation and diversified portfolio have allowed us to proactively mix bits into the most profitable end markets, resulting in sequential revenue growth and margin improvement across both Flash and HDD.
These growth opportunities are bolstered by the AI data cycle substantially increasing the long-term need for storage across both our Flash and HDD markets. In Flash, the proactive measures we took during the downturn along with our disciplined capital investment strategy have significantly enhanced Western Digital's business agility and structural margin potential. Combined with our flexibility and bit allocation and continued progress in bringing highly compelling enterprise SSDs to market, we mitigated headwinds in certain core end markets, achieving sequential and year-over-year revenue growth and improving flash gross margin beyond our through-cycle target. In HDD, the strength of our portfolio lies in our UltraSMR technology, which empowers us to deliver the industry's highest-capacity hard drives while ensuring unmatched reliability, quality, and performance.
Western Digital has achieved record HDD gross margin in the highest revenue levels in 11 quarters, driven by the growing adoption of our UltraSMR drives to meet the demand for scalable and cost-effective storage solutions. This technology is a key driver of our continued gross margin improvement with wide adoption of two cloud customers and a third expected to ramp shortly. We anticipate Ultra SMR will continue to grow across the U.S. and beyond, solidifying our leadership in the market over time.
Now, I would like to provide an update on our business separation plans. We are on track with the separation of our Flash and HDD businesses. At the start of the fiscal second quarter, we completed our soft spin phase. Through meticulous planning and project management, this massive initiative has been executed exceptionally well and the businesses have hit the ground running, thanks to the dedicated efforts of numerous teams over the past year.
In the fiscal second quarter, we continue to execute our soft spin stage and are working diligently on the critical work streams needed as we make significant progress on the regulatory filings required in connection with the spin. Financing activities are anticipated to start soon, which will set the stage for us to execute the separation, which we expect will occur once we close the second quarter. I'll now turn to business updates. Starting with Flash, revenue reached its highest level in nine quarters.
Sequentially, revenue growth was driven by continued recovery in data center fueled by strong demand for our enterprise SSD applications, which grew 76% sequentially, reaching the highest revenue level since fiscal fourth quarter of 2022. The cloud tailwind in the quarter was offset by ongoing weakness in consumer and in client with PC OEMs working down inventory and pushing out the refresh purchase cycle. On the technology front, we made significant progress with several hyperscaler and storage OEM qualifications, including developments with PCI Gen 5 data center enterprise SSD and our 30- and 60-terabyte high-capacity offerings. In addition, we continue to enhance our premium SanDisk brand by delivering on our leadership blueprint and core devices road map, expanding our platform capabilities with product partnerships developing robustly.
I'll now turn to our flash outlook. As we look ahead to the fiscal second quarter, we expect the continued ramp of our new enterprise SSD offerings to supplement seasonal strength in our consumer end market. Within client, we expect PC OEM demand to stabilize while gaming declines as we have successfully met the demand for the holiday season. We anticipate a recovery in our consumer and client end markets as we move through calendar year 2025.
Furthermore, we are seeing high demand for our enterprise SSD product offering and anticipate it to serve as the primary driver for revenue growth for the full fiscal year. With qualifications doubling since the start of the fiscal fourth quarter 2024, we now expect our enterprise SSD mix to comprise over 15% on of our overall portfolio shipments in fiscal year 2025, growing at a pace significantly faster than previously anticipated. Our overall view of the flash market remains positive as we maintain supply and demand balance by remaining committed to disciplined capital spending and improving profitability through a proactive bid allocation across our most high-value end markets, increasing our exposure to enterprise SSDs. Turning to HDD.
In the fiscal first quarter, we achieved record revenue in data center, reflecting the strength of our nearline portfolio and our ongoing efforts to capitalize on market tailwinds. We are operating in an environment where demand for our products exceeds supply. To address this, we are working with our customers to improve our visibility into their future needs with our largest customers on a two- to six-quarter agreement cycle, aligning seamlessly with our proactive supply management strategy that supports predictable business operations and sustainable profitable growth. This long-term visibility allows us to not only better serve our customers but also mitigate volatility while structurally improving our through-cycle profitability.
On the technology front, we see increasing adoption of our Ultra SMR technology, showcasing strong confidence in our products' capabilities and benefits. In the fiscal second quarter, we launched our 32-terabyte UltraSMR and 26-terabyte CMR drives, marking the world's first commercially available hard drives with 11 disks. Developed with our time-tested and reliable ePMR and UltraSMR technologies, we expect these products to complete customer qualifications and ramp in the coming quarters delivering a compelling TCO to our customers and improving portfolio profitability. Turning to the HDD outlook.
As we head into the fiscal second quarter, we anticipate continued momentum in data center to drive growth across our nearline portfolio. Adoption of our UltraSMR product line is expanding particularly among cloud customers. The HDD business continues to undergo a positive structural transformation. Our thoughtful approach to commercializing our product line, especially our UltraSMR technologies, has enabled us to drive record revenue in the midst of AI's emergence as another pivotal growth driver for the industry.
And with improved visibility into future demand, a focus on operational excellence, efficient cost structure, and a strong commitment to maintaining a balanced supply demand dynamic, we are well-positioned to continue delivering the most profitable and innovative product portfolio while establishing long-term industry leadership through our earnings potential. Let me now turn the call over to Wissam, who will discuss our fiscal first-quarter results.
Wissam G. Jabre -- Executive Vice President, Chief Financial Officer
Thank you, David, and good afternoon, everyone. In the fiscal first quarter, Western Digital delivered great results with gross margin and earnings per share above the midpoint of the guidance range. Total revenue for the quarter was $4.1 billion, up 9% sequentially and 49% year over year. Non-GAAP earnings per share was $1.78.
Looking at end markets, Cloud represented 54% of total revenue at $2.2 billion, up 17% sequentially and more than doubling year over year. On a sequential and year-over-year basis, the increases were driven by higher nearline shipments in HDD and enterprise SSD bit shipments to data center customers. Client represented 29% of total revenue at $1.2 billion, flat sequentially and up 5% year over year. Compared to last quarter, Flash bit shipment growth in gaming and mobile was offset by a decline in PC OEM, while HDD revenue was flat.
Year over year, an increase in Flash revenue was primarily due to higher ASPs as bit shipments declined and was partially offset by lower HDD revenue. Consumer represented 17% of revenue at $0.7 billion flat sequentially and down 7% year over year. Sequentially, a slight growth in HDD offset a decline in Flash driven by softer consumer demand. Year over year, the decrease was due to lower flash and HDD bit shipments, partially offset by improved pricing in both flash and HDD.
Turning now to revenue by segment. In the fiscal first quarter, Flash revenue was $1.9 billion, up 7% from last quarter and 21% year over year. Continued recovery in data center drove strong demand for enterprise SSD products. Sequentially, Flash ASPs increased 4% on a like-for-like basis and decreased 6% on a blended basis.
Bit shipments were up 14% from the previous quarter and down 12% compared to last year. HDD revenue was $2.2 billion, up 10% sequentially and 85% year over year. Sequentially, Strong performance in the nearline portfolio led to a 14% increase in HDD exabyte shipments. On a year-over-year basis, total HDD exabyte shipments increased 107% and average price per unit increased 46% to $164.
Nearline bit shipments were at a record level of 141 exabytes, up 12% from the previous quarter and 157% compared to the fiscal first quarter of 2024. Moving to the rest of the income statement. Please note my comments will be related to non-GAAP results unless stated otherwise. Gross margin for the fiscal first quarter was 38.5%, which was at the higher end of the guidance range.
Gross margin increased 220 basis points sequentially due to improved mix, better pricing, and continued focus on cost reduction. Flash gross margin was 38.9%, up 240 basis points sequentially, driven by a higher mix of enterprise SSD bits improvement in like-for-like pricing and continued cost reduction. In HDD, strong demand for nearline drives as well as efficient manufacturing operations and cost structure, have driven continued margin expansion, resulting in gross margin of 38.1%, up 200 basis points sequentially. We have structurally changed the way we operate our businesses.
Combined with our strong product portfolio, this has enabled us to generate gross margins above our long-term target ranges in both Flash and HDD. Operating expenses were down sequentially to $691 million, including the synergies of $8 million. These results demonstrate continued focus on cost discipline while making progress on the execution of the business separation plans. Operating income was $884 million, up 33% sequentially, driven by better gross margins and disciplined spending.
Operating margin was 21.6%, up 390 basis points sequentially, which is the highest in five years and was previously achieved at a higher revenue level. Income tax expense was $124 million, and effective tax rate was 16.1%. Earnings per share was $1.78. Operating cash flow for the fiscal first quarter was $34 million, and free cash flow was an outflow of $14 million.
Operating and free cash flows included payments of $418 million for the company's repatriation, tax installment along with IRS settlement payments. Cash capital expenditures, which include the purchase of property, plant and equipment, and activity related to flash joint ventures on the cash flow statement, represented a cash outflow of $48 million. Fiscal first quarter inventory increased sequentially to $3.4 billion, with days of inventory declining by five days to 121 days. A decrease in HDD inventory was more than offset by an increase in Flash inventory.
Gross debt outstanding was $7.5 billion at the end of the fiscal first quarter. Cash and cash equivalents were $1.7 billion, and total liquidity was $3.9 billion, including undrawn revolver capacity of $2.2 billion. After the close of fiscal first quarter, we completed the previously announced sale of 80% of equity interest in SanDisk Semiconductor Shanghai to JCET. Thereby forming a joint venture between SanDisk China and JCET.
Proceeds from the sale will be reflected in the fiscal second quarter's cash flow. I'll now turn to the fiscal second quarter non-GAAP guidance. We anticipate both Flash and HDD revenue to grow on a sequential basis. In Flash, we expect the ramp of enterprise SSD products and seasonality of consumer demand to drive bit shipment increases in the mid-single-digit percentage points.
In HDD, we expect continued growth momentum in the nearline product portfolio. We anticipate revenue to be in the range of $4.2 billion to $4.4 billion. Gross margin is expected to be between 37% and 39%. We expect operating expenses to increase slightly to a range of $695 million to $715 million, including the synergy costs of $25 million to $35 million as we continue to make progress executing on the business separation plans.
Interest and other expenses are anticipated to be approximately $110 million. Tax rate is expected to be between 15% and 17%. We expect EPS of $1.75 to $2.05 based on approximately 357 million shares outstanding. As shown in our guidance, we remain committed to executing our business, driving higher profitability and cost discipline while making great progress toward the completion of our business separation plans.
I'll now turn the call back over to David.
David V. Goeckeler -- Chief Executive Officer
Thanks, Wissam. Let me wrap up, and then we'll open up for questions. Our results this quarter are a testament to our efforts to optimize our business for the long term and execute on our strategic initiatives. We are confident in our product road map across both our Flash and HDD businesses.
and are excited by the significant opportunities ahead that each present, especially with the continued proliferation of the AI data cycle. As we continue to work toward the completion of our business separation plans, we are confident in our ability to drive long-term shareholder value and deliver the most compelling and innovative products to our customers. Let's begin the Q&A.
Questions & Answers:
Operator
Thank you. Ladies and gentlemen, we will now begin the question-and-answer portion of today's call. [Operator instructions] One moment please for the first question. And our first question today comes from C.J.
Muse with Cantor Fitzgerald. Please go ahead.
C.J. Muse -- Analyst
Yeah. Good afternoon. Thank you for taking the question. I guess, first question, you raised your enterprise SSD as part of the mix of 15%, which I think is a pretty important inflection.
So, I was hoping you could speak to the qualifications that you've seen. And in particular, would love to hear more around the recently announced qualification with NVIDIA's GB200 NVL72 rack system. If there's any way to kind of quantify how to think about the ramp and magnitude of incremental dollars to your business would be great.
David V. Goeckeler -- Chief Executive Officer
Hey, C.J., thanks for the question. Yeah, we feel really good about where the portfolio as we've talked, I think, for a quarter or so now about this, our compute-focused PCIe Gen 5 product. That's what was qualified by NVIDIA in their reference architecture that allows us to go to all the folks that are building those products for customers and be in a good position to have those conversations as we drive that product more broadly in the market. We also have a very deep engagement with one -- well, a couple of large hyperscalers on that product as well.
So, to your point, we've got more confidence in the growth of the portfolio. It's a very good demand environment. That's -- I don't think that's new news for enterprise SSDs. And it's nice to have the portfolio where we can play into that.
And as you said, we expect our mix of bits when we add it all up at the end of the fiscal year, last quarter when we were having this conversation, we thought it would be around 10%, and now we're more in the 15% to 20% range. So, demand keep going up, the number of qualifications we doubled in the last quarter. So, the traction with the portfolio is it's good. It's all aligned well with the AI data cycle we put out there, both for the compute-focused SSDs and then the high-capacity data lake-focused SSDs, 30 and 60 terabytes.
And again, the traditional products that we were selling to the hyperscalers are also doing well. So, just I think that portfolio is something we've been working on for quite some time. As you know, we got qualified before the downturn, we came out of it with a better portfolio. I think we really did a good job.
Teams did a great job throughout the downturn of staying focused on building those products and building a stronger portfolio and now we're seeing the results of that.
C.J. Muse -- Analyst
Very helpful. Thank you. And I guess as a quick follow-up, you talked around the ongoing transformation of the HDD industry and now two to six quarters of customer visibility, would love to hear kind of how perhaps pricing negotiation is evolving. And within that construct, do you have visibility today for pricing beyond one quarter in the Drive business? Thank you.
David V. Goeckeler -- Chief Executive Officer
Sure. I think as you said, we've gotten to the point where I think we have better supply demand balance in this industry for the first time. Well, let's just talk about our business and our business for a very, very long time based on the actions we took coming out of the downturn, that matched against a fantastic portfolio that continues to get traction. We talked a lot about it in the script.
Our UltraSMR technology is really getting very good traction with the customers that have adopted it at quite a bit of scale. I mean, once you go to the work to implement that technology, you get that additional 10% of capacity on every drive every drive you deploy. So, it gives customers a very good reason to keep deploying those drives, and we just had the third hyperscaler, get the official qualification very recently, and we expect them to ramp pretty quickly now over the next several quarters. So, both of those things allow us to get more visibility into the business.
More visibility, more predictability is always great on a business where we're vertically integrated. And it does give us also -- I've said it for many years now, pricing is all about TCO. It's about delivering a better product. We deliver a better product that drives the TCO down for our customers, we get to participate in that equation and monetize that R&D that we developed.
And we just launched a 26-terabyte CMR, 32-terabyte UltraSMR drive. So, we expect that to ramp as we go through '25. And as we do that, that will bring better pricing and margin dynamics to the business.
C.J. Muse -- Analyst
Thanks so much.
David V. Goeckeler -- Chief Executive Officer
Thanks, C.J.
Operator
Thank you. And our next question today comes from Joe Moore of Morgan Stanley. Please go ahead.
Joe Moore -- Analyst
Great. Thank you. I just want to make sure I understand the steps toward separating the companies. You talked about having kind of prepared to soft spin.
So, you're going to report, you'll have two separate sets of numbers for the December quarter. And assuming that that goes well, you'll be able to file the Form 10 at some point during the March quarter. Is that the plan? And kind of what are the -- anything that could cause that to come later?
David V. Goeckeler -- Chief Executive Officer
Yeah. Let me walk through that, Joe, because it's a little different than you described. So, we will -- we're in the soft spin stage, which means we're still running the company as Western Digital, right? There's one company. But behind the scenes, we've separated all the systems into basically two stacks of systems.
So, for example, if customers want to send us orders now, they have to send us two different orders for HDD and Flash because they go into two different sets of systems. They have a different vendor ID for those, all of those kinds of issues. Our own teams as they go to the process to build those products, ship those products are logging into different systems to manage the flow of that business through the enterprise. Now, in -- so what we're doing is we're running Western Digital.
We're doing this behind the scenes. That's called the soft spin, were actually -- essentially do both. And what we'll do is we will execute in this mode for a full quarter because we want to go through a full quarter of all the financial things we do on a monthly and quarterly basis to give ourselves confidence that both of those systems work great, and then we'll go do the spin. So, what we expect to do now is -- we will execute the business in this form for the full second quarter.
We will close the December quarter as Western Digital. We only issue one set of numbers for Western Digital. We only did one guide for Western Digital this time. But behind the scenes, we're doing all that work to build confidence we could do it as two separate companies.
Sometime in the next, I would say, a couple of months, we'll make -- we'll flip the Form 10 to public. We're going through the final phases of that with appropriate authorities. Once we get that done, we'll make it public so we can start financing activities for both businesses to basically get all the financing in place so that we -- once we close the books, and we get confidence in that, then we could then move on with the actual distribution. So, that's the way it will work.
So, cut through all that, we got a lot of work to do. It's on track. You should think about this happening around the time we would do an earnings call for the December quarter.
Joe Moore -- Analyst
Great. Thank you so much for that. And I guess I get a lot of questions from more event-driven types of investors about the resolve to do this in the wake of things that are happening with our JV partner, and things like that. So, just maybe if you could just kind of state how focused you are not getting this done, any impediments? Any chance that this doesn't happen from -- out of your discretion?
David V. Goeckeler -- Chief Executive Officer
Well, we're very focused on getting this, John -- Joe. As you know, we went through a thorough strategic review that we announced the outcome of October 30 of last year, and we started down this path. We knew it was a big thing to do. But we're not -- the results of the strategic review is this is the right answer for our shareholders.
We're not trying to time the cycle or anything else. So, we plan to move forward with this when we're ready. And it's all about building confidence in the ability to execute to independent companies, and that's what we're driving to. I can't predict everything that will happen in the future, but that's -- from our perspective, we're driving to get this done as expeditiously as we can.
Joe Moore -- Analyst
Great. Thank you very much.
David V. Goeckeler -- Chief Executive Officer
Thanks, Joe.
Operator
Thank you. Our next question comes from Karl Ackerman of BNP Paribas. Please go ahead.
Karl Ackerman -- Analyst
Yes. Thank you. I have two if I may. First off, how much room do you have in your existing facilities to expand capacity of heads and media for hard disk drives? I asked if you just reported record exabytes and hard drives less about 180.
And as you address that question, you spoke of a third hyperscaler that is qualified SMR, Dave, and it will ramp in the coming quarters. Is that for your 32 TB offering, or is that just a broad statement? Thank you.
David V. Goeckeler -- Chief Executive Officer
You know, I think there's a general -- without getting into specifics on any particular customer, I think in general, most customers want to go with the most dense drive they can once they start deploying. So, we expect that customers will move to the 32-terabyte drive pretty quickly. Again, I think this is -- the product strategy, I think, is really playing out well here. These drives can be qualified very quickly.
Customers understand the technology. It's been their environment for quite some time. So, I'm talking about the base ePMR technology and the base architecture we have in these drives and now we can move capacity up quickly. So, in general, customers want to deploy the densest drive possible.
So, we expect the 32s as they -- once they get through qualifications, we'll start being deployed, let's say, as we move through '25. On your first question on capacity for heads and media, I mean, we don't really talk about what our capacity is. We sized our infrastructure for a number of units we think is going to satisfy the market, and then we're going to increase exabytes by continuing to drive innovation and more density per unit. You're seeing that happen in real time as we just launched a new drive.
And we've got the capacity all the way through head and media and test capacity and assembly to support that level of capacity. And that was really a big move in the downturn to get it right. And so, that we can get our -- make sure we keep our costs under control. And then, Karl, the real focus is to get more visibility from our customers and what their plans are and planning so that we can make sure we've got that capacity aligned what demand is and try and dampen some of the volatility of the typical we typically talk -- or maybe not anymore, hopefully not any more talk about big ingestion cycles, then big digestion cycles.
We want a more predictable business than that, so we want to -- you know, the key to that is visibility into customer demand.
Karl Ackerman -- Analyst
Very clear. Thanks.
David V. Goeckeler -- Chief Executive Officer
Thanks, Karl.
Operator
And our next question today comes from Aaron Rakers with Wells Fargo. Please go ahead.
Aaron Rakers -- Analyst
Yeah. Thanks for taking the questions. I'll stick to two as well. I guess the first question is going back to kind of operating the two entities separately now starting in this October period, can you just remind us again of how we should think about dissynergies? What may be factored into your December quarter guide as clearly you're carrying two company cost structures? And then as kind of a follow-up to Karl's question, you are shipping nearline capacity 25% above your prior peak levels, if my math is close to being right, how much does it -- how quickly can you bring on new capacity? And is there any way to frame like I could appreciate technology and aerial density expansion is a key driver? But do you see a situation where you will be constrained over the foreseeable next couple of quarters? Or just -- I'd love to dig a little bit deeper into Karl's question there.
Wissam G. Jabre -- Executive Vice President, Chief Financial Officer
So, let me start with the first part of the question, Aaron. I think your question was on dissynergies. So, in the first quarter that we announced, we had approximately $8 million of dissynergies in the operating expenses. And the guide, there is 25% to 35% roughly -- sorry, this is -- I take that back.
There is $25 million to $35 million, not percent of opex assumed -- in the opex in the current guide. In other words, the 705 midpoint of opex includes approximately, let's say, midpoint $30 million. Basically, as we said last time, these synergies are assumed to be roughly split 50-50 between the two operating businesses. And so, this is what's in the guide.
In terms of where we would be at the steady state, I would say, at this point, it hasn't changed from what we discussed last quarter and the steady state anticipate to be roughly in the, let's say, $40 million range divided equally by each of the businesses. So, that's how we should think of it beyond this quarter. But for this quarter, it's around $30 million, plus or minus $5 million. Maybe for the second part of your question, I don't know, David.
Maybe I'll start making some comments and I'll ask David to chime in. With respect to the manufacturing capacity, our focus in the hard drive business, as we've said all along, is really on driving profitability. And maintaining that supply demand balance for our business. And so, as we -- from where we stand now, we think we have -- with the good visibility that we're getting from our customers and the implementation of build-to-order, we think we're in a good place from a capacity or from a manufacturing capacity perspective, and we don't see the need for us to expand our manufacturing capacity footprint.
I don't know, David, if you had a few things to add.
David V. Goeckeler -- Chief Executive Officer
No, I think that's right, Aaron. I mean, look, I mean, at least the way I think about this capacity if you look at the units we've shipped in the last two or three quarters, it's all converged pretty closely. So, there's not a lot of variability in that number. It goes up and down some like less than 1 million units.
But for an industry that shipped hundreds and hundreds of millions of units, not that long ago, that's a pretty tight window. I think the way we're thinking about this is what's demand going to be a year from now? It takes a year to build a hard drive once we start a wafer, no matter what our wafer capacity is for heads once we start a wafer, it's going to be a year before that shows up in a hard drive. So, what we really are working to understand is what demand is going to be a year from now and how our customers are thinking about that, and that's something new for them, right? And we're working through that process with them. And everything is going in the right direction.
We talked about we have between two and six quarters of visibility, as we continue to get more visibility and develop conviction about what demand is going to look like over the next year plus, then we'll start looking at the capacity question and if it's different than what we planned, we'll think about capacity at that point. But we -- there's still more work to do to understand what capacity is going to look like in that kind of time frame before we start adding that cost back into the system. We don't want to -- I talked about in the script, better through cycle dynamics -- we don't want underutilization charges. We want more predictable flow of business in our supply chain wants that, too.
So, that's just a little bit on how I'm thinking about it.
Aaron Rakers -- Analyst
Very helpful. Thank you, guys.
David V. Goeckeler -- Chief Executive Officer
Thanks, Aaron.
Operator
Thank you. And ladies and gentlemen, we do ask that you please limit yourself to one question at a time in the queue. Our next question today comes from Timothy Arcuri with UBS. Please go ahead.
Timothy Arcuri -- Analyst
Thanks a lot. Can you just talk about bookings on the HDD side? I mean, they see pricing going higher. They see you and Seagate talking about not adding capacity. So, why would they not just place shadow orders to make sure they get what they need a year from now? I mean, that's often how it works in memory.
I certainly understand that the cycle times here are much, much longer. But can you talk about that? And sort of what is this two- to six-quarter agreement cycle mean? Are these take-or-pay so that they can't just place shadow orders that they'd be on the hook to take the stuff when you build it? Can you talk about all that? Thanks.
David V. Goeckeler -- Chief Executive Officer
Yeah. Tim, I would say the industry is evolving, right? This is something new. I mean, this is an industry that wasn't that long ago while the business transacted every quarter. So, we're asking customers more visibility understanding what their demand is.
They haven't particularly thought about this franchise that way and getting that much visibility into it. And they're big relationships, especially with the big hyperscalers, like very, very big relationships. Nobody wants to yank each other around unnecessarily. So, I think it's in all of our best interest to have as much visibility as possible so that we can supply the market.
We don't want to short the market, but we also don't want to basically build capacity that we don't have visibility into how it's going to be used. So, at this point, it's not a take or pay. It's just about getting visibility into kind of how they're thinking about their infrastructure and what their demand is going to be. So, we know how much supply we're going to have the ability to produce from a unit perspective that we get that aligned with their demand.
And I would say we're working through that process right now. And I mean, clearly, the more visibility people our customers and partners can give us, then we can allocate that future supply to them. And it's just kind of the process we're going through right now. So, it's -- we're kind of walking to this and changing the industry, we think, in a very positive way for everybody involved.

Thank you. And our next question today comes from Wamsi Mohan with Bank of America. Please go ahead.
Wamsi Mohan -- Analyst
Hi. Yes. Thank you so much. Your guidance just a slight tick down in gross margins at the midpoint sequentially.
Can you just help us think through the drivers of that? And you obviously launched our 11th platter mass capacity drive, too. How should we think of margins with that scale higher as you go through the course of fiscal '25? Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. So, you got it right, Wamsi, that as we introduce new products, we have the opportunity to drive margin higher. We just launched a new product. It will just start qualification, so it's not going to start for deployment for another couple of quarters.
So, in the HDD business, we're going to see margins basically flat Q to Q. Flash, we'll see a little bit down driven by some -- the cost in the next quarter are a little bit up from what they usually would be for what you guys model on a 15% down year over year. We're going to get a quarter we have a little cost increase just given the way the expenses are flowing. So, I think that should help you understand the way the margins are going to work.
Operator
Thank you. And our next question today comes from Harlan L. Sur with JPMorgan. Please go ahead.
Harlan Sur -- Analyst
Hey, good afternoon. Thanks for taking my question. So, on enterprise SSD, it's taken a while, but now there's clarity on the really strong tie-in, right, to these AI-accelerated compute clusters, can you give us your view on bit mix? But I think according to my calculations, I think June quarter, I think enterprise SSD was about 7%, 8% of your total Flash rev, it looks like in the September quarter, it stepped up to about 12%, 13% of your Flash revenues, is that about right? And then on some of the recent specs on your high-capacity 64-terabyte, 128-terabyte platforms targeted for AI. Looks like the team has really set up their competitiveness here.
What have been the biggest drivers of that better performance? Is it controller technology? Is it firmware? Is it reliability, quality metrics? Like any color here would be great. Thank you.
Wissam G. Jabre -- Executive Vice President, Chief Financial Officer
Yeah. Let me start with the first part of the question, Harlan. With respect to where we are from an enterprise SSD as a mix, we're basically with -- in the Q1, we've exceeded a little bit the 15% of that mix. And as David mentioned in his in his comments a bit earlier that we would expect for the year, the mix of enterprise SSD as a percent of total for the Flash business to be between 15% and 20%.
David V. Goeckeler -- Chief Executive Officer
So, Harlan, on the competitive part, I mean, you kind of -- you got it, right? I mean, it's about getting the controller technology right. And we -- as I said during the downturn, we stayed very focused on that. We've got the right controllers built. We've always had great underlying NAND technology.
The BiCS road map is something we've talked about a lot. And we feel good about that now. And going forward, we still got all the BiCS8 in front of us and that two-terabit die that helps build higher-density enterprise SSDs as well because the lower number of die to get the density. We're not quite there yet, but we have that in our future.
So, it's about getting it all of it aligned. And we stayed very focused over the last two, three years since I got here. This was a big focus of, again, going back to how we structured the company into kind of a business unit model, bringing in a general manager that can stay very focused on what should be built, stay on top of all the programs, and make sure we deliver the right products that drive the -- make the highest ROI investments and then make sure those products -- those projects deliver the right products to market. And I think we're -- we feel good about where we're at, we're hitting this AI data cycle with the right -- it's the right time for the portfolio to emerge.
We still got some more work to do, but we feel good about where we're at and the trajectory.
Operator
Thank you. And our next question today comes from Krish Sankar with TD Cowen. Please go ahead.
Krish Sankar -- Analyst
Yeah. Hi. Thanks for taking my question, and Dave, thanks for the color. You know, when I look at December quarter, you said flash revenue should grow, while bit shipment should be up mid-single digits.
So, what does it mean for ASPs? The reason I'm asking is that while eSSD is strong, you keep hearing the non-eSSD data points are not good. So, that's why I'm wondering how to think about ASP. And if I may extrapolate, how do you think about March quarter for both Flash and hard drives, given there is some seasonality aspect for both those segments in March? Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. Krish, so you got -- I mean, again, I think you've got it in the way you framed your question. The Flash market is a big market. There's a lot of submarkets inside of it.
The PC market is some inventory there, and those customers restocked and have not replenished inventory. They're just building to demand at this point same with smartphone, the consumer business has just been a little bit soft. So, you've got kind of that dynamic. And then on the other side of it, you've got very, very strong enterprise SSD.
Now, we expect -- as we go through '25, we expect those smartphone and PC markets to recover as we go throughout the year and be stronger, we can talk about that in more detail, but I think that's a well-understood topic. And we expect enterprise SSD to stay very strong. But when you -- then you look at it on a sequential basis, you're looking at basically flat blended pricing and a little bit of cost headwind which is where you get a little bit of sequential decline in margins. Going -- it's a little early to talk about the March quarter.
But again, you got it right on seasonality there. There might be some seasonality hit. I would some seasonality headwinds going into the March quarter. But we'll have more to say about that as we move through the quarter and especially get to this time next quarter, OK?
Operator
Thank you. And our next question today comes from Amit Daryanani with Evercore. Please go ahead.
Amit Daryanani -- Analyst
Thanks for taking my question. I guess, David, if I just go back to this 100 -- the exabyte shipment of 163 on the HDD side, how do you get confidence that this is not sitting in inventory versus actually getting deployed by your customers? Is there any metrics you see internally that gives you confidence that -- this is actually getting used up and not piling up as inventory potentially? Anything on that front would be really helpful to understand. And then Wissam, you just touch on your capex expectations for HDD and the Flash for the rest of the year, that would be helpful. Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. We don't see a lot of inventory at the big players, right? We're coming off of -- we're still like in a cyclical recovery from the very deep, deep downturn we're coming out of. And we're very, very close to these customers, given the size of the relationship. So, we don't think that there is inventory -- excessive inventory being built here or double ordering or any of that happening.
We think everybody is just trying to figure out what their future demand is so we can make sure we do the best we can to meet it, and they give us the best -- the highest integrity signal possible on what that demand is.
Wissam G. Jabre -- Executive Vice President, Chief Financial Officer
Yeah. And with respect to the capex, Amit, the -- what we started doing last quarter is, as we're talking about capex for the quarter. So, for this quarter, I expect our gross capex to be more or less in line with the last few quarters, the average over the last few quarters. So, there's no real inflection.
Operator
Thank you. And our next question today comes from Thomas O'Malley with Barclays. Please go ahead.
Tom O'Malley -- Analyst
Hey, Dave and Wissam, thanks for taking the question. I just wanted to ask for you to help quantify the benefit on the eSSD side versus the traditional NAND portfolio. Obviously, you're saying that that grows from 15% today to 20%, so nice tailwind throughout the year. But just on a like-for-like basis, could you just try to help describe what that tailwind means? Obviously, you're not going to give an exact pricing away, but just give us a favor for how beneficial that is of the business.
Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. It's accretive to the portfolio. Let's put it that way. And that's a good starting point.
You probably knew that. It tends to be one of the better, if not the best price markets in the Flash business. So, it provides a nice tailwind to the portfolio.
Operator
Thank you. And our next question today comes from Srinivas Pajjuri with Raymond James. Please go ahead.
Srini Pajjuri -- Analyst
Yeah. Thank you. David, just to follow up to the previous question, I'm looking at your Flash ASPs being down 6% on a blended basis. But on a like-for-like basis, it's only down 4%.
So, it seems somewhat counterintuitive because your SSD mix is growing, but the blended ASP is actually worse than like-for-like. So, just trying to understand those dynamics as to why that's the case. And as I guess, SSD grows, how should we think about the blended ASP going forward? Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. So, I think it's even a little different than what you said. I think you said down 4% on like-for-like. Like-for-like was up for blended it was down 6%.
So, it's all mix-related. I think we said going into this quarter, we were mixing more into mobile. Clearly, as we mix in more enterprise SSD that helps. But that's an emerging story and an attendant story for us.
And so, that's why you see that dynamic there.
Operator
Thank you. And our next question today comes from Asiya Merchant with Lupe Capital. I apologize. Our next question comes from Ananda Baruah with Loop Capital.
Sorry about that. Please go ahead.
Ananda Baruah -- Analyst
No, I appreciate it. Thanks for taking the question.
David V. Goeckeler -- Chief Executive Officer
Hi, Ananda.
Ananda Baruah -- Analyst
Hey, Dave. Yeah, I was just -- could you -- actually, what I wanted to ask is can you refresh our memory on what your conventional technology aerial density road map looks like kind of up until HAMR? I know you've talked about HAMR loosely kind of like next few years. But how should we think about the conventional tech aerial density road map up until then? That would be helpful. Thanks a lot.
David V. Goeckeler -- Chief Executive Officer
Well, that's a very interesting area to explore. One thing is, as it changes over time as you keep getting better. And I think a good example of that is we just introduced an 11 platter drive, I think for a long time, people thought 10 was probably the limit given the form factor, but advances in material science and things like that allow us to build thinner platters, and we can put an 11th in, and there you go, you get 10% more just by doing that. So, it's always an evolving story.
But we clearly see the ability to drive our current platform to 40 terabytes to make that bridge from 30 to 40. We're driving through that now. And that's where we expect HAMR to be introduced to carry the portfolio from there. So, we've still got a generation or so here to go.
We just announced one generation that just came into the market this quarter. Customers are excited about it. They have it in the labs. They're trying to get it qualified.
They want to get it deployed. I'm not going to announce a new product here right now, but you can assume there's going to be another generation after that. So, we've got quite a bit of runway on the portfolio. And those drives are drives that customers really understand -- they're in their infrastructure now.
They're -- it's a straightforward qualification process. They understand the performance, they understand the reliability, the quality of those drives. So, really feel good about the technology decisions we've made to kind of fuel this market, and now we have kind of these AI tailwinds behind it. I think the portfolio is just extraordinarily well positioned to continue to drive growth in the business and then continue to drive increased profitability.
Operator
Thank you. And our next question today comes from Asiya Merchant with Citigroup. Please go ahead.
Asiya Merchant -- Citi -- Analyst
Great. Thank you for taking the call -- taking the question. So, just in terms of HDDs, I understand that the strength here, continued strength here in the December quarter, we typically see some seasonality on the Flash side in the March quarter, just given strength you're seeing on the HDD side, should we expect some seasonality here in the March quarter on the HDD side as well, both in terms of bit shipments and then also on the ASP side. Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. I mean, it's a little early for March, but I don't think that's a bad assumption to make at this point from where we are to see that on the HDD side as well.
Operator
Thank you. And our next question today comes from Steven Fox of Fox Advisors. Please go ahead.
Steven Fox -- Analyst
Hi. Good afternoon. I was just wondering if you could provide a little bit more color into the manufacturing efficiencies you think you get on a regular basis out of the HDD business. I would imagine there's debottlenecking still going on.
And also, as mix changes, it helps the utilization on the heads and platters side. So, I don't know if there's any rule of thumb we can think about. Or just maybe a little more color on that would be helpful. Thank you.
Wissam G. Jabre -- Executive Vice President, Chief Financial Officer
I mean, the way to think of it is we typically have obviously many programs in terms of cost reductions, which would drive manufacturing efficiency as well as things like improving yields, etc., at various parts of the supply of our manufacturing sort of process. The typical -- I mean, I don't know if there's a typical, but the way to think of it is we will still be getting in the cost improvements and the probably mid- to high single-digit percentage on an annual basis. That will be probably a fair assumption. But of course, it varies, of course, with respect to how we move from one capacity point to another as well.
So, it's not like a linear thing.
Operator
Thank you. And our next question today comes from Vijay Rakesh with Mizuho. Please go ahead.
Vijay Rakesh -- Analyst
Yeah. Thanks. Just a quick question on the UltraSMR terabyte. Are you -- with the 11th disk, are we able to still make it accretive on the margin it to your current portfolio? And also on the Flash side, just wondering what the capex looks like for next year.
This year, I think you had like a 0.8 fairly low cash outlay on the capex side, but just wondering how it looks next year. Thanks.
David V. Goeckeler -- Chief Executive Officer
Yeah. I mean, the 32-terabyte UltraSMR drive is a perfect example of us delivering a drive to our customers. It drives our TCO down. So, as we drive their TCO down, it will drive our profitability up.
And so, we're very anxious to get that drive deployed, just like our customers are, and we expect that will provide some profitability tailwinds to the business.
Wissam G. Jabre -- Executive Vice President, Chief Financial Officer
Yeah. And with respect to the flash capex, as I mentioned earlier, we're not providing sort of a longer-term view in terms of quantitatively, what I would say is we're continuing to be focused on the profitability of the business. And so, our focus is really to drive cost down, but when you look at capex, last fiscal year, our capex was very, very low. So, we'd expect it to be a little bit higher from there.
Operator
Thank you. And our final question today comes from Matt Bryson with Wedbush. Please go ahead.
Matt Bryson -- Wedbush Securities -- Analyst
Thanks for taking my question. What I was wondering is your hard drive pricing was relatively stable quarter over quarter. I would have thought with the greater shipments into the cloud as well as the mix-up toward higher capacity drives, you would have seen a little bit of a benefit there. And then just one more point.
I know you've talked about there being production constraints. One of the things that I've heard as being a constraining factors test, Paradigm is telling us that they're not seeing any test orders, should we take that as a sign that the hard drive industry is adding in a more rational session than in the past? Thank you.
David V. Goeckeler -- Chief Executive Officer
Yeah. I mean, look, on the second part of the question, I think we've just been pretty clear. We've kind of set our manufacturing capacity for a certain number of units. We think that unit times what our product road map is, is going to satisfy the exabyte growth in the industry and we're good with where we're at.
And again, if we get strong enough signals from our customers, that four- to six-quarter time frame, then we'll -- we can start talking about what that means for our production capacity, but we got a ways to go before we get something like that. On pricing, we did see a little bit of like-for-like pricing increase, very low single digits this quarter. It was a good quarter for margin improvement again in HDD, 38.1%, another record I think we've added over 15 points of margin in the last four quarters. So, it's been a good run.
We'll take a little breather here maybe for a quarter. And then as new products get deployed, we'll see more tailwinds behind that. So, we just feel like this business is in a great spot. And quite frankly, that's because our technology is in a spot, and it's really being adopted strongly by our customers.
They're very much voting with their dollars behind the architecture that we're driving. And then during the downturn, the teams just did an awesome job of really getting our costs in the right spot to support this business and get supply demand balance. So, we feel good about the business, and we look forward to driving it forward over the next several years.
Operator
Thank you. That concludes the question-and-answer session. I'd like to turn the conference back over to the management team for any final remarks.
David V. Goeckeler -- Chief Executive Officer
All right, everyone. Thanks for joining today. I really appreciate the interest in the business and all the great questions, and we look forward to talking to you throughout the quarter. Take care.
