Western Digital: Sales of Helium-Filled HDDs Accelerating, 15M Sold So Farby Anton Shilov on May 13, 2017 3:00 PM EST

Western Digital recently announced that it had sold 15 million helium-filled hard drives, indicating that sales of such HDDs are accelerating. Since the launch of the HGST HelioSeal platform about 3.5 years ago, it has enabled HGST to make a number of technological improvements to its hard drives in terms of their capacities. It is noteworthy that while Western Digital is expanding usage of helium, it has not announced plans to expand usage of shingled-magnetic recording (SMR).
HGST, a subsidiary of Western Digital, started volume shipments of its first-generation helium-filled Ultrastar He-series hard drives in November 2013. HGST sold about a million HelioSeal HDDs in the first 1.5 years on the market, but once numerous operators of large cloud datacenters qualified such drives, their sales started to accelerate. For example, HGST supplied 1.1 million of helium-filled HDDs in Q3 2015 — more than in their first six quarters on the market. Meanwhile back in October of last year, Western Digital said it had sold 10 million HelioSeal hard drives. As it appears from the recent comments made by the company, in just a couple of quarters it has managed to sell another five million helium HDDs with cumulative shipments of such drives topping 15 million units since late 2013.
“I am pleased to note that we have now shipped approximately 15 million helium hard drives cumulatively since the platform's launch four years ago,” said Michael D. Cordano, president of Western Digital, during a conference call with investors and analysts.
There are multiple reasons why sales of HelioSeal-based HDDs are accelerating. First, the demand for datacenter hard drives is growing, and operators have finally qualified helium-filled HDDs for new deployments. Second, with the systematic increase of drive capacities (a new capacity point is launched every 12 – 18 months), Western Digital can gradually increase shipments of helium-filled drives to existing and new deployments. Third, Western Digital is expanding usage of helium beyond datacenter-class drives to NAS and even consumer HDDs.
From technology standpoint, HelioSeal has made quite a bit of progress in the recent 3.5 years. Initially, it enabled HGST to place seven platters into a single 3.5” HDD and offer a 6 TB drive, which in turn had lower power consumption and higher performance than various competitors. Installation of seven platters into one drive required HGST to redesign some of the internal HDD components, and this is always a challenge. Moreover, late last year HGST introduced an even denser hard drive, the Ultrastar He12 with eight platters, which again required the company to redevelop internal architecture of the HDD.
When it comes to practical progress, the helium-filled Ultrastar drives doubled their capacity from 6 TB in Q4 2013 to 12 TB in Q1 2017. By contrast, conventional air-filled PMR-based drives have not yet made it past 8 TB, increasing their capacity by 33% from 6 TB in Q1 2014. Meanwhile, if we take the SMR-based Ultrastar He12 with 14 TB capacity into account, then the progress will seem quite impressive as well (a 75% increase from 8 TB in August 2013 to 14 TB in 2H 2017).
Speaking of SMR, it does not look like Western Digital is eager to share its plans regarding usage of the technology.
“Shingle [magnetic recording] has been a little bit more limited in terms of the applications because of some of the performance implications of that and that sort of thing,” said Stephen Milligan, CEO of Western Digital. “We feel comfortable with where we are at in terms of SMR transition and the applicability and the drives that we are providing to our customers.”
Unlike drive-managed SMR HDDs from Seagate, SMR HDDs from Western Digital should be managed by hosts and are therefore used only for active archive/deep-archive applications that can support it. This reduces their addressable market, but the company still sells plenty of them: 20 – 35% of data stored today belongs to the two aforementioned categories. Meanwhile, Seagate offers drive-managed SMR-based HDDs for both consumers and datacenters, something that Western Digital does not. For the time being at least, it looks like the company is not planning on disclosing any kind of roadmap for drive-managed SMR devices.

Beaver M. - Sunday, May 14, 2017 - linkSo can we expect lower prices on 8+ TB HDDs then? Even the cheapest one is still as expensive as 3 years ago. And even my 2 & 4 TB HDDs still cost as much as when I bought them 6 and 3 years ago.
I am starting to suspect price fixing.

HomeworldFound - Sunday, May 14, 2017 - linkStupid keyboard. I've been thinking like you lately. The hard drive market has been running very slow. It wasn't until 4TB SSD's were announced that the latest jump happened. The mainstream storage manufacturers finally bought / opened SSD divisions and released their own line of SSDs.
I'm very surprised that they aren't making 50TB drives by this point. Maybe I was being unrealistic but it was four or five years ago scientists were talking about 1000TB holographic discs.
voicequal - Sunday, May 14, 2017 - linkCloud providers are buying up all the high density HDDs which is supporting prices. I would expect HDD prices to continue to increase as they become more of a niche technology for data archival - most of which is moving into the cloud.
ats - Monday, May 15, 2017 - linkReduced competition and increased high capacity demand with reduced low capacity demand. Basically, the cloud vendors have been buying every topline capacity drive they can for the past 3-4 years effectively propping up demand for that segment. Meanwhile the rest of the market has pretty much been replaced by SSDs. That combination means that the vendors have little to no incentive to sell cheaper than the cloud vendors will pay and there is no motivation to drop max capacity prices in the wholesale/retail market.
You can find cheap drives but they tend to be seconds/defect drives sold into the white label or portable/removable market.
DanNeely - Monday, May 15, 2017 - linkSSD penetration is nowhere near as high as "he rest of the market has pretty much been replaced by SSDs". I can't find any numbers from this year (probably too soon to have aggregated even the Q1 data yet); but at the end of last year they were only projecting half of all PCs and an eighth of desktops sold this year would have them. Penetration is near ubiquitous in the enthusiast market; but outside of it sticker price is the most important factor. That is followed by bigger numbers which HDDs win because ###GB/TB goes on the sticker; not mixed (read/write and variable data chunk size) IO throughput at QD 1.
sorten - Sunday, May 14, 2017 - linkThis is no laughing matter.

RubiNBA - Monday, May 15, 2017 - linkEverything went well until after 3 months the first drive failed. It actually happened right in front of me. I was monitoring the server stats when the IOwait spiked when the server was apparently doing nothing. I checked the logs and found that the drive was refusing commands. Being somewhat annoyed at the infant mortality of the drive, I decided to buy a Hitachi as the replacement. I can’t say exactly why, it might have been a bit more expensive but I don’t remember. About 6 months later, I decided to expand the array to 7 drives and purchased another Hitachi of the same model as the one prior, seeing how it fared so well.
