When you’ve used a solid-state drive (SSD) you’ll by no means return. Those that know the distinction between a tough drive and random-access memory (RAM) would simply perceive why. An SSD is actually a tough drive manufactured from RAM, so it’s lightning-fast and consistently accessible. Booting up turns into a factor of the previous as a result of there aren’t any shifting components, and you may open and shut your laptop computer at will with out creating any issues together with your purposes. It’s straightforward to think about a future the place laborious drives turn into out of date as a result of they’ve been changed by SSDs. Whereas it’s not a blue ocean alternative, it’s nonetheless a thesis price taking a look at due to this outdated hockey stick.
Synthetic intelligence algorithms are solely pretty much as good as the massive information you feed them. AI chipmaker NVIDIA (NVDA) is aware of this nicely. It’s why they pushed to broaden their information middle section with the acquisition of Mellanox such that it now accounts for 40% of complete revenues. Our latest piece on information middle REITs talked about how the demand for warehouses to retailer all this massive information is coming from all instructions together with massive cloud suppliers like Amazon, Google, and Microsoft. So, why don’t we spend money on the units used to retailer massive information, like laborious drives?
HDDs vs. SSDs
Hard disk drives (HDDs) are the standard technique of storing information and so they’ve been round for many years. Intel spells it out concisely.
HDDs are a legacy storage expertise that use spinning disks to learn/write information. SSDs are quicker and extra energy environment friendly than HDDs. HDDs are priced decrease, however SSD costs are dropping.

So, our thesis goes one thing like this. Demand for information storage might be rising over time no matter whether or not information facilities are being constructed by REITs or cloud suppliers. Information won’t cease being generated if the economic system hits the skids, so it appears to be a reasonably resilient thesis. If we’re going to spend money on laborious drives, then there are three corporations to contemplate which dominate almost all the market – Toshiba, Western Digital, and Seagate.
There’s nothing disruptive about investing in commodity computing {hardware}, however perhaps we will skate to the place the puck might be. In the present day, 30% of non-archival storage makes use of SSDs, and a few material specialists consider that would attain 80% by 2025.
By 2025, the most cost effective flash storage could also be 2.5 instances dearer than the most cost effective laborious drives, nevertheless it might additionally permit for two.5 instances better compression, so the associated fee will steadiness out.

The Benefits of SSDs
The particular person behind the above quote believes that superior efficiency is why finally SSDs will disrupt conventional HDDs together with different facets of information storage. Information storage tapes are nonetheless being utilized in massive information facilities to offer chilly storage backups. In some unspecified time in the future in time, it’d make sense to switch these tapes with laborious drives which permit restoration to happen a lot quicker, to not point out the velocity at which SDD backup media would possibly be capable to function. Everybody would favor that each main and backup information storage would use SSDs, it’s only a operate of value. That’s as a result of enterprise cloud suppliers search for three main options when buying information storage {hardware} – value, reliability, and efficiency.
Firms like Confluent (CFLT) that analyze information in real-time would discover efficiency to be a critically essential characteristic since time is of the essence. Tomorrow’s predictive analytics purposes like these on supply from C3.ai (AI) can present insights faster by accessing the info faster. An more and more massive variety of enterprise software program use instances will look to {hardware} for higher efficiency. There’s additionally a inexperienced component to contemplate since SSDs eat much less energy. (Extra on the associated fee benefits in a bit.)
Information centre SSD revenues will enhance 24.9 per cent CAGR from $7.74bn in 2019 to $23.5bn in 2024. Exhausting disk drive revenues will decline at -3.8 per cent CAGR.

By 2025, a lot of the world’s saved information will reside within the public cloud, in accordance with analysis from IDC. Meaning SSD {hardware} for information facilities must be a very good area of interest to spend money on. Development for SSDs is about displacing antiquated storage applied sciences and leveraging the general development of information storage services, however we don’t like the thought of investing in a commodity {hardware} product that decreases in value yearly.
The {Hardware} Drawback
It’s all the time price contemplating what applied sciences is likely to be across the nook. DNA information storage appears promising when it comes to capability and reliability, however maybe not efficiency. The actual fact we’re nonetheless utilizing magnetic-tape information storage expertise from the Nineteen Eighties implies that information storage options have some sturdiness. The expansion of SSDs looks as if a compelling thesis, however we run into the identical drawback we see with investing in {hardware} corporations like SolarEdge. There have to be some high-margin recurring income streams that may preserve the pig fats when the margins on commodity {hardware} dry up.
We additionally want to contemplate the uncooked inputs used to supply SSDs – NAND flash reminiscence. An article final February by Ars Technica talks about how contamination at two factories in Japan might have an effect on the availability of flash reminiscence.
Stable-state storage units have up to now been spared from the shortage and excessive costs that the chip scarcity has wrought upon graphics playing cards, vehicles, Raspberry Pi boards, and innumerable different merchandise. However that will change quickly, due partially to a “contamination” at two Japanese factories utilized by Western Digital and Kioxia to make flash reminiscence.
Ars Technica
It’s not the primary time there’s been a flash reminiscence scarcity. Again in 2017-2018, costs of flash reminiscence stopped dropping and even elevated barely due to an industry-wide scarcity.
If you’re promoting a bodily product the place pricing is reducing sharply over time, your margins are consistently below stress, and also you’re topic to dangers from the suppliers of bodily inputs. It’s simply another excuse to like software-as-a-service (SaaS) corporations.
Flash-Native vs. SSD
The agency that produced the above chart, Wikibon Analysis, revealed an in depth analysis piece late final 12 months on The Enterprise Case for Flash-native which proposes further components to contemplate when doing a cost-benefit evaluation for HDD vs. SSD. For instance, some corporations are forgoing the SSD drives on supply from distributors and using the uncooked NAND flash chips to permit for fully novel designs which take efficiency to the subsequent degree. Such a {hardware} known as “Flash native” is “way more environment friendly than SSD architectures in managing the native and distant copies of information, optimizing information placement, and managing a number of ranges of NAND expertise.” From the shopper’s perspective, they’re shopping for SSD drives {that a} vendor has custom-made to carry out significantly better than SSD drives on supply from the standard suspects. When you think about complete value of possession over a ten-year time-frame, Wikibon Analysis believes that Flash-native comes out forward.
Says the analysis agency:
Wikibon believes {that a} Flash-native strategy, the place the first bought ingredient is just the flash chips, will result in extra flexibility and decrease prices. As well as, Wikibon believes that the foremost cloud suppliers are additionally engaged on Flash-native storage options.

Conclusion
Investing in conventional information storage strategies like HDDs or magnetic storage tapes doesn’t seem to be a viable pick-and-shovel play on the expansion of massive information within the coming years. The transfer in the direction of storing the world’s information within the cloud, coupled with the rising want for efficiency and reliability, implies that SSDs for information facilities are an interesting funding thesis if we will discover a vendor that enhances their {hardware} with high-margin recurring revenues. In a coming piece, we’ll check out an organization that’s growing their very own flash-native {hardware} providing with a lovely recurring income stream.
