Pure Storage: No More Hard Drives Will Be Sold After 2028 (blocksandfiles.com) 154
An anonymous reader shares a report: In the latest blast of the HDD vs SSD culture wars, a Pure Storage exec is predicting that no more hard disk drives will be sold after 2028 because of electricity costs and availability, as well as NAND $/TB declines. Shawn Rosemarin, VP R&D within the Customer Engineering unit at Pure, told B&F: "The ultimate trigger here is power. It's just fundamentally coming down to the cost of electricity." Not the declining cost of SSDs and Pure's DFMs dropping below the cost of disks, although that plays a part. In his view: "Hard drive technology is 67 years old. We need to herald this technology that went from five megabytes the size of this room to where we are today. And even the latest HAMR technology, putting a laser on the top of the head in order to heat up the platters, is pretty remarkable ... But we're at the end of that era."
HDD vendors sing a different tune, of course. Back in 2021, HDD vendor Seagate said the SSD most certainly would not kill disk drives. There's a VAST vs Infinidat angle to it as well, with the former also stating disk drive IO limitations would cripple the use of larger disk drives in petabyte-scale data stores, with Infidat blasting back that it "must be joking." Gartner has had a look in too, claiming that enterprise SSDs will hit 35 percent of HDD/SSD exabytes shipped by 2026 - though that would make Rosemarin's 2028 cutoff unlikely. Pure recently stated SSDs would kill HDDs in a crossover event that would happen "soon." Rosemarin, meanwhile, continued his argument: "Our CEO in many recent events has quoted that 3 percent of the world's power is in datacenters. Roughly a third of that is storage. Almost all of that is spinning disk.
So if I can eliminate the spinning disk, and I can move to flash, and I can in essence reduce the power consumption by 80 or 90 percent while moving density by orders of magnitude in an environment where NAND pricing continues to fall, it's all becoming evident that hard drives go away." Are high electricity prices set to continue? "I think the UK's power has gone up almost 5x recently. And here's the thing ... when they go up, they very seldom if ever come down ... I've been asked many times do I think the cost of electricity will drop over time. And, frankly, while I wish it would and I do think there are technologies like nuclear that could help us over time. I think it'll take us several years to get there. We're already seeing countries putting quotas on electricity, and this is a really important one -- we've already seen major hyperscalers such as one last summer who tried to enter Ireland [and] was told you can't come here, we don't have enough power for you. The next logical step from that is OK, so now if you're a company and I start to say, well, we only have so much power, so I'm gonna give you X amount of kilowatts per X amount of employees, or I'm gonna give you X amount of kilowatts for X amount of revenue that you contribute to the GDP of the country or whatever metric is acceptable."

Let's assume both SSDs and HDDs cost zero for a minute, just for a mental exercise.

Getting me a nice ~2PB in 4U space.
Densest NVMe datacenter storage I could find is 32 disks in 1U space:
https://www.supermicro.com/en/... [supermicro.com]
And it supports up to 4TB per slot, giving us 128TB in 1U, or 0.5PB in 4U.
Not too bad in terms of density.
However that 2PB system is 2600watts, while 4x1U nvme is 6400watts. A significant portion comes from the system itself, meaning the motherboards, controllers, CPUs, RAMs, which have to be duplicated. (Denser NVMe is limited by PCIe bandwidth. It would still require more nodes and/or more CPUs per node).
So if you are looking for pure storage area, even ignoring costs, NVMe would cost more during operation.

Comparing power like that doesn't make sense, as the NVME system has a significant higher throughput. In fact, when you throttle them to the performance of the HDDs, they should be no worse.
Comparing throughput doesn't make sense, either, though, because not all storage requires high throughput.
Think about how much low-access-rate bulk user data (photos, movies, etc.) is stored in "the cloud". Most of it won't get accessed more than once a week. So as long as you optimize your storage so there aren't very many high-throughput users per server, HDDs are potentially fast enough to make the number of simultaneous users per server be bounded by capacity rather than performance, so speeding up the storage won't let you put more users' data on a node.
Over time, SSDs will replace HDDs for more and more use cases, and at least theoretically that means that the cost of building HDDs with higher and higher density will be borne by fewer and fewer purchasers, which will slowly drive their cost per terabyte up over time, while the cost of increasing SSD density will be borne by more and more purchasers, which will drive their cost per terabyte down.
However, you can't infinitely stack more silicon, both for heat dissipation reasons and power consumption reasons, so increasing SSD density is bounded in part by increasing semiconductor density, which is getting harder and harder to improve. That has the potential to slow the transition.
Hard drives hit their sales peak way back in 2011 [statista.com]. In the 12 years since, however, sales have dropped by only a factor of four, and that's with approximately every laptop on the market switching to SSDs. Sales are still at late-1990s levels, despite a huge drop in corporate cloud storage needs in 2022.
Additionally, there isn't enough manufacturing capacity available to support the sudden replacement of HDDs with SSDs universally right now. So as SSDs become cheaper, the corresponding increase in demand will tend to support their price somewhat, making the crossover point where SSDs become cheaper than HDDs likely to be farther out than simple cost-based extrapolation would suggest.
At the current rate, 2028 seems rather optimistic to me, with SSDs from companies I've never heard of running ~3x as much per terabyte as large enterprise HDDs, and reputable SSDs running more than 5x the price of HDDs with capacity closer to the price-per-terabyte sweet spot. I could easily be wrong. I'd like to be wrong. But that doesn't seem likely to me.

If you mostly read data, it will be lower. If you deliberately reduce the PCIe link rate, it will be lower. If you only do occasional reads and most drives are sat idle most of the time, your power consumption over time will probably be a lot lower than what is needed to keep a load of discs physically spinning.

There are different markets for storage. Twenty years ago, flash wiped out the mobile device storage market for HDDs. Ten years ago, SSDs wiped out the high-speed, low capacity enterprise HDD market. Five years ago, SSDs wiped out the laptop market for HDDs.
The total addressable market for HDDs is obviously shrinking, but it's not clear that it will go all the way to zero. The big remaining HDD market is cold/warm storage, like for the huge amounts of storage for something like Facebook that is accessed

I wish people who say silly things like these would put some money on it. I'd like to wager $1k worth of storage that hard drives will definitely not only still be around, but will still be the preferred storage medium for high endurance.

Holo storage comes and goes. We had Tamarak in the 1990s with that, then about ten years later, another firm with holographic storage drives... which never made it to market. This is sort of the fusion of the tech world... always 10-20 years out.
It would be really nice to have though. We need a high density optical WORM format that has ECC and resilience from physical damage, as well as high/low temperatures, as something to compete against tape, and ideally something cheap enough that SOHO users could u

Of course, there are those who swear by analog having some qualitative benefit that digital doesn't have. So for audio and photography you'll have those who will hang on to them.
For digital data storage? It's easy to show that the SSDs are just objectively better if price/capacity ever reaches parity. There are scenarios where HDDs are good enough for the cost savings. It is true that there is a market for things like the HDD Clicker to fake the noise from disks, but they generally strive for the sound

Well, somewhat recently there was an article here that the lifetime energy consumption of HDDs is higher than that of SSDs, because the manufacturing takes so much energy. The amount of energy consumed by HDD is just a few watts, after all. It is a tiny portion of what a computer consumes. Often it is cheaper to invest to power efficiency of other components. In data centers, the storage is on all of the time, each HDD will consumed about 55 kWh/year, and for a life span of about 5 years, that is 275 kWh. I

But I think the share of HDDs will reduce. Data centers will probably be those using them the longest.

My work is moving to local SSDs on server hardware and planning on moving to SSDs on shared file systems in the next few years.
Higher cost of SSDs is less than facilities' increased cooling and power costs.
0.88% of world's power(4% of electrical power). (Score:2)
From https://en.wikipedia.org/wiki/... [wikipedia.org]
Total final consumption (TFC) is the worldwide consumption of energy by end-users. This energy consists of fuel (78%) and electricity (22%)
According to https://www.engie.com/en/campa... [engie.com]
The data center industry accounts for around 4% of global electricity consumption and 1% of global greenhouse gas emissions.
So data centers use about 22%*4%=0.88% of the world's power.

"Maybe if the NSA didn't record and archive every citizens phone calls and emails..."
Let's assume that's true. So, how much storage would that require?
With texting, phone use has seriously decline over the decades, but let's overestimate and assume each citizen talks for an hour/day to another citizen and there are ~330M US citizens. That would mean there are ~165M hours of conversations to record/day. And audio can easily be stored at 1Mb/minute, so that totals 165M * 60 (convert to minutes) * 1Mb; which equals ~9.9B Mb, or ~10TB/day. That's right, a $200 10TB drive could easily hold a day's worth of every single phone call made in the US. And that's assuming everyone has an hour phone call every single day.
Emails could have similar numbers. Text only email take nearly zero space, but attachments can add up. If each person emailed as much data daily as that 1 hour phone call, that would total emailing ~60Mb per day. Few people do this. Therefore another 10TB drive could likely contain all the email (before compression) sent to/from US citizens daily.
NAS servers can hold 12+ disks, so with mirroring a server could hold about a week's worth of phone/email usage for the US. 13 servers to a rack would mean 4 racks could hold a year's worth of that data. A small data center could hold every phone call and email ever sent within the US and it could be replicated elsewhere for redundancy. So, if the NSA were recording all that data, it wouldn't have any more impact on the nation's power usage than a medium sized business.
