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 made from RAM, so it’s lightning-fast and continually accessible. Booting up turns into a factor of the previous as a result of there are not any shifting components, and you’ll open and shut your laptop computer at will with out creating any issues together with your functions. It’s simple to think about a future the place arduous drives turn into out of date as a result of they’ve been changed by SSDs. Whereas it’s not a blue ocean alternative, it’s nonetheless a thesis value due to this outdated hockey stick.
Synthetic intelligence algorithms are solely nearly as good as the massive information you feed them. AI chipmaker NVIDIA (NVDA) is aware of this properly. It’s why they pushed to broaden their information middle phase with the acquisition of Mellanox such that it now accounts for 40% of whole revenues. Our current piece on information middle REITs talked about how the demand for warehouses to retailer all this large information is coming from all instructions together with giant cloud suppliers like Amazon, Google, and Microsoft. So, why don’t we spend money on the units used to retailer large information, like arduous drives?
HDDs vs. SSDs
Hard disk drives (HDDs) are the standard methodology of storing information they usually’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 shall be growing over time no matter whether or not information facilities are being constructed by REITs or cloud suppliers. Information is not going to cease being generated if the financial system hits the skids, so it appears to be a reasonably resilient thesis. If we’re going to spend money on arduous drives, then there are three corporations to contemplate which dominate almost your complete market – Toshiba, Western Digital, and Seagate.
There’s nothing disruptive about investing in commodity computing {hardware}, however perhaps we are able to skate to the place the puck shall be. In the present day, 30% of non-archival storage makes use of SSDs, and a few subject material consultants imagine that might attain 80% by 2025.
By 2025, the most affordable flash storage could also be 2.5 instances dearer than the most affordable arduous drives, but it surely might additionally enable for two.5 instances higher compression, so the fee will stability out.

The Benefits of SSDs
The individual behind the above quote believes that superior efficiency is why finally SSDs will disrupt conventional HDDs together with different features of knowledge storage. Information storage tapes are nonetheless being utilized in giant information facilities to supply chilly storage backups. Sooner or later in time, it’d make sense to interchange these tapes with arduous drives which permit restoration to happen a lot quicker, to not point out the pace at which SDD backup media would possibly be capable of function. Everybody would like that each major and backup information storage would use SSDs, it’s only a operate of price. That’s as a result of enterprise cloud suppliers search for three major options when buying information storage {hardware} – price, reliability, and efficiency.
Corporations like Confluent (CFLT) that analyze information in real-time would discover efficiency to be a critically necessary function since time is of the essence. Tomorrow’s predictive analytics functions like these on provide from C3.ai (AI) can present insights faster by accessing the info faster. An more and more giant variety of enterprise software program use circumstances will look to {hardware} for higher efficiency. There’s additionally a inexperienced factor to contemplate since SSDs eat much less energy. (Extra on the 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. Laborious disk drive revenues will decline at -3.8 per cent CAGR.

By 2025, a lot of the world’s saved information will stay within the public cloud, in response to analysis from IDC. Which means SSD {hardware} for information facilities ought to be a very good area of interest to spend money on. Progress for SSDs is about displacing antiquated storage applied sciences and leveraging the general development of knowledge storage services, however we don’t like the thought of investing in a commodity {hardware} product that decreases in price yearly.
The {Hardware} Downside
It’s at all times value contemplating what applied sciences is perhaps across the nook. DNA information storage appears promising when it comes to capability and reliability, however maybe not efficiency. The very 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 downside we see with investing in {hardware} corporations like SolarEdge. There must 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 provide 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 provision of flash reminiscence.
Stable-state storage units have thus far 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.
Once you’re promoting a bodily product the place pricing is reducing sharply over time, your margins are continually 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, printed an intensive analysis piece late final yr on The Enterprise Case for Flash-native which proposes extra elements to contemplate when doing a cost-benefit evaluation for HDD vs. SSD. For instance, some corporations are forgoing the SSD drives on provide from distributors and using the uncooked NAND flash chips to permit for utterly novel designs which take efficiency to the subsequent degree. One of these {hardware} known as “Flash native” is “way more environment friendly than SSD architectures in managing the native and distant copies of knowledge, 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 personalized to carry out a lot better than SSD drives on provide from the same old suspects. When you think about whole price of possession over a ten-year timeframe, Wikibon Analysis believes that Flash-native comes out forward.
Says the analysis agency:
Wikibon believes {that a} Flash-native method, 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 key 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 huge information within the coming years. The transfer in the direction of storing the world’s information within the cloud, coupled with the growing want for efficiency and reliability, signifies that SSDs for information facilities are an interesting funding thesis if we are able to discover a vendor that enhances their {hardware} with high-margin recurring revenues. In a coming piece, we’ll check out an organization that’s creating their very own flash-native {hardware} providing with a horny recurring income stream.
