"Of all the many thousands of computer companies I’ve written about in the past 26 years of publishing - Seagate is the company which has moved furthest along the SSD adoption curve - compared to its originally interpreted position. It shows that successful companies can adapt and learn and then master new business models which once seemed to threaten their very existence. I’m bowing out from commenting about the memoryfication market soon. But Seagate’s journey in SSD is one I’ll remember." - Zsolt Kerekes, editor - (July 2018)

Seagate renews custom supply agreement with Baidu
Editor:- September 18, 2017 - Seagate - which has admitted being negatively impacted by the memory shortages of 2017 and which sells SAS SSDs through its memory partner Micron (although "the quantity is not huge" - according to a recent article on and anyway this legacy SAS enterprise segment is under attack from new competitors using Nimbus's reference design platform - today announced a new strategic agreement with Baidu which renews and expands an earlier collaboration agreement announced 3 years ago.

Among other things Seagate says - "With regard to new products, Baidu will be at the forefront of Internet users in China implementing Seagates new storage products, and also the 2 sides will jointly develop customized systems to meet Baidu business needs. In addition, the procurement model for both companies will be further upgraded to save costs for each side."

Editor's comments:- In an SSD market predictions article Dec 2015 I said - "The urge towards greater customization will be driven by the need to improve the efficiency of SSDs (cost of raw materials and competitiveness) and also technical characteristics (performance, power consumption, reliability etc) which are optimized specifically for well defined application specific needs."

In the next few years storage users and suppliers need to make plans for a memory ecosystem in which the traditional assumptions about downward memory pricing and ample availability may be invalid. These trends will drive all data factory industries to look at opportunities to increase efficiency which - at system scales - will benefit from custom rather than standard design products.

Editor:- November 28, 2016 - Seagate was ranked #2 in the new 2016 Q3 edition of the Top SSD Companies List which is researched and published by

This is Seagate's highest rank in this series.

Seagate first appeared in the Top SSD Companies in 2010 Q3

who's who in SSD? - by Zsolt Kerekes, editor - September 2014

In 2014 there was a dramatic transformation for Seagate with respect to how it was viewed in the SSD market - due to its acquisition of the SSD business of LSI.

Prior to this - and throughout the entire first decade of the enterprise flash SSD market - Seagate was not considered by SSD insiders like myself to be a heavyweight SSD company - despite its entry in the Top SSD Companies searched list at #12 in Q1 2010.

The reasons for that being a combination of factors including:-
  • the company's habutual downplaying of the importance of SSDs
I discussed the market changes which can be expected from Seagate augmenting its own SSD business development activities by leveraging the SSD and SSD controller business acquired from LSI in May 2014 when news broke of the agreement.

Seagate's rank at #10 in the most searched SSD companies by readers of in Q2 2014 - moving up 9 places to acheive its best rank (upto that time) in the 7 year history of this industry tracker - was a signal that the SSD market recognizes the strategic significance of the changes in Seagate - and now expects to see much more from this company.

When comparing the new SandForce driven Seagate with other leading enterprise SSD competitors - a superficial competitive analysis by detractors may lead you to think that Seagate still has some apparent weaknesses compared to its PCIe SSD rivals. But how valid are they? Here are some examples: of such questions.
  • Seagate - unlike Micron, SanDisk and OCZ - doesn't have its own flash.

    Is that really a problem?

    In the short term - I don't think it's a problem at all.

    I have often said on these pages that pure play SSD companies - can have advantages by being able to pick and choose the newest or cheapest flash - and not being tied to a flash memory fab.

    The SandForce design team - who have been responsible for the widest penetration of SSDs into diverse applications anywhere in the world so far - has proven that its designs are flash agnostic. And so long as Seagate stays out of the flash market and increases its focus on SSDs - there are many advantages to be gained by the flexibility which comes from not having its own flash.
  • Seagate - unlike SanDisk and OCZ doesn't have a strong SSD software platform.

    It could be argued that neither does Micron or Intel - and it hasn't stopped their products being widely used by oems in the enterprise market.

    In some markets - having an SSD product line which isn't tied to a strong software personality - can be a competitive advantage - as seen from the systems design perspective. For more about why - see my article on the complexities of rackmount SSD market segmentation.

    On the other hand - as we've seen in the recent history of SSD acquisitions - that short term weaknesses in SSD software can be fixed by buying a suitable company. And there's no shortage of new software companies which are doing interesting things in the SSD market.
To sum it all up.

No SSD company is perfect and no SSD company has everything needed by the different needs of the SSD market. But I now feel confident in saying that the new SandForce driven Seagate has the potential to remain a long term resident within the Top 10 SSD Companies List (companies which you absolutely have to look at if you've got any new projects involving SSDs).

That's a huge about face from me - as you can see by reading what I've written about Seagate's activities in the SSD market in the years before the recent big changes at the company.
Seagate SSD milestones from 30 Years of SSD Market History

In April 2008 - Seagate launched an SSD patent suit against STEC. This attempt to stall the SSD market by scaring wannabe oems was unsuccessful.

In December 2009 - Seagate entered the SSD market and announced details of its Pulsar SSD - a 2.5" SATA SLC SSD with 200GB capacity.

Sequential R/W rate is upto 240MB/s and 220MB/s respectively, R/W IOPS are 30,000 and 25,000 respectively. Aimed at the server market the BER is quoted as 1 sector per 10E16. Seagate says it has been sampling the new drive - its 1st SSD - since September 2009.

In January 2010 - LSI and Seagate announced they have collaborated on designing PCIe SSDs for the enterprise accelerator market which will sample in Q2 2010.

In May 2010 - Seagate launched the Momentus XT a 2.5" hybrid drive - for the notebook PC market - which internally has a 500GB HDD cached by a 4GB SSD ASAP controller. Seagate said the new drive is OS agnostic and delivers SSD-like performance at the lower price of a hard drive.

In August 2010 - Samsung and Seagate announced they will jointly develop SSD controller technologies to operate with Samsung's 30nm-class MLC NAND. The jointly developed controller will be used in Seagate's enterprise-class SSDs.

In January 2011 - Seagate was ranked #13 in the top 20 SSD companies list - its highest position since the series began 4 years ago.

In March 2011 - Seagate announced details of new 2.5" SAS SSDs - marketed under its Pulsar brand - which will ship in the 2nd quarter.

Available capacities are 400GB (SLC) and 800GB (MLC). R/W speeds are upto 360MB/s and 300MB/s respectively. Sustainable random R/W IOPS are 48K and 22K respectively.

In June 2012 - Seagate announced it will use DensBits's flash care technology in the design of forthcoming consumer and enterprise SSDs. Seagate has also made an equity investment in DensBits.

In January 2013 - Seagate made a strategic equity investment in Virident as part of a new collaboration agreement which includes remarketing Virident's PCIe SSDs and working together to design new SSDs for the enterprise market. However, despite that - Virident Systems was later acquired by WD's enterprise SSD subsidiary - HGST for approximately $685 million in cash.

In May 2014 - Seagate agreed to acquire LSI's flash business for $450 million.

who's who in SSD? - by Zsolt Kerekes, editor - February 2013

Seagate is a Top 20 SSD Company.

Seagate's position in the development of the SSD market upto now has been that of a follower of, investor in, and integrator of 3rd party SSD IP rather than an originator of leading SSD technologies. Seagate's highest rank to date in the top SSD companies list was #11 in Q1 2011.

Seagate was a comparatively late entrant to the SSD market launching its first SSDs in December 2009. But Seagate was already corporately aware of SSDs - having launched an unsuccessful lawsuit aimed at STEC the year before.

Why didn't Seagate's dominance in the hard drive market translate into an early dominance in SSDs too?

(In case you need reminding - Seagate was the world's largest HDD maker during the time that companies like SandForce, Fusion-io and Violin were launching their first products.)

But Seagate's failure to engage constructively with the SSD market at a critical time in the modern SSD era was noted by many SSD market commentators.

Among the possible root causes for what SSD history will interpret as a missed early opportunity for Seagate to make its own mark in steering the direction of the SSD market are these factors.
  • Seagate misunderstood the potential size of the SSD market opportunity - and didn't think it was important enough compared to other business opportunities in hard drives.

    In early 2011 - in keeping with the tone of a multi-year series of "SSD-denier" style corporate marketing communications which started hitting newswires and blogs (and mysteriously disappearing again) in the apologetic years before before Seagate had any SSDs of its own to talk about ("but you wait and see - when Seagate does SSD - we will be the best") - Seagate in January 2011 - finally offered to the world a hard hitting rebuttal to the SSD-taking-over-the-world view in an economics focused paper which argued that the reason hard drives would remain the dominant storage technology was because - the company reassured us - it would cost far too much for the SSD market to invest enough resources into replacing hard drives. was not alone in thinking - but maybe was alone in asserting so aggressively - that Seagate's analysis and vision was NUTS!.

    We said - if users see unbeatable business advantages from SSDs (something we had already analyzed and demonstrated longe before) - then the necessary investments would be made to support the larger SSD ecosystem.
  • when Seagate did begin to realize that the SSD market wasn't going to go away - the SSD market had already grown too complicated for Seagate to understand what was going on and Seagate was in no position to entertain the idea of becoming a credible technology leader.
It's likely that a root cause of Seagate's wrong footedness in SSDs in the 2003 to 2011 years was due to the company's management mistakenly viewing SSDs as just an expensive specialized form of hard drive.

Seen from that perspective hybrid drives and co-existance look like a better solution than they do from a pure SSD perspective.

As Seagate didn't develop an adequate SSD IP set of its own - the company's first SSD products relied heavily on 3rd party IP from LSI and SandForce. However after LSI's acquisition of SandForce in January 2012 it soon became clear that LSI was perfectly capable of getting storage oem customers such as EMC and Intel on its own. It didn't need Seagate as a route into the SSD market.

More recently - 2012 and 2013 - Seagate has therefore been pursuing the only realistic options left to latecomers in the SSD market - acquisition, licensing 3rd party IP and badge engineering.

Examples of this activity include:-
  • - licensing IP from the adaptive R/W flash company - DensBits (announced in June 2012) and
  • and oeming the PCIe SSD product line and related enterprise SSD software from Virident (announced in January 2013)
I have applauded these recent steps as positive moves - either of which - if followed through - could improve Seagate's position within the SSD world.

But SSD is a very competitive and complex set of markets. Even pure SSD companies - which don't have other distractions - have a tough enough time understanding what's the right way to go with products and markets. And I'm still not convinved that Seagate takes SSDs as seriously as it should.

Looking ahead at the challenges and opportunities posed by the SSD market for Seagate - I think that having to share management time and investment resources between the mutually different interests of solid state and magnetic drive product lines will lead to tensions and conflicts for resources in which the corporate "compromize solutions" aren't always going to be the same as the best of class solutions which the SSD market expects.

What's still lacking at Seagate (and they aren't the only company in this predicament) is a fiery SSD core which has the ambition to take on the (SSD) world.

Because in the modern era of SSDs - the only thing which can beat an SSD in the market - is another - better SSD. In that context - knowing how to design and build the best or cheapest hard drives - and having routes to market for hard drives is - frankly - irrelevant.
how big will the SSD market be when SSDs replace all enterprise hard drives?

Seagate chooses DensBits for TLC and 1Xnm
Editor:- June 25, 2012 - Seagate announced today it will use DensBits's flash care technology in the design of forthcoming consumer and enterprise SSDs.

Seagate has also made an equity investment in DensBits.

Editor's comments:- I've already written more than enough about about this technology trend recently the article - Adaptive flash care management & DSP IP in SSDs.

As DensBits told us a few months ago - their business plan is work with companies which sell complete SSDs - instead of licensing their technology to other controller makers. DensBits's technology spans the widest spectrum of adaptive DSP flash SSD applications from consumer and industrial to fast-enough enterprise SSDs.

If Seagate leverages DensBits's flash technology successfully - the result will be tougher competition for companies like SanDisk in the consumer SSD market and tougher competition for STEC and SMART in the fast-enough enterprise SSD market.
don't all PCIe SSDs look pretty much the same?
When you look at the photos and headline specs for high speed PCIe SSDs - it's easy to come away with the impression that they all look the same and have about the same performance.

After all - how different can they be?

But don't let the experience of the 2.5" SSD market - in which clusters of consumer SSD vendors use the same or similar controllers and hover close together inpopular (consumer) performance rankings - give you the wrong idea about PCIe SSDs.

In this market the performance limits and capabilities of the SSD aren't set by an old hard disk interface and package limitations.

In the PCIe market the products you get are limited only by the imagination of the designers - tempered by the guesses of marketers who are trying to predict the optimum (most salable) features for an ideal SSD.

"Re the nand shortages... I think it's probably more challenging for the technology industry to deal with the shortages than it is maybe beneficial for HDDs because of some comparison on say some 500GB drive.... It's not easy to say if it's good or bad... We've always said it's a better world if there's a lot of nand because that means people have more devices in their hands and they're creating more data."
Stephen Luczo, Chairman and CEO - Seagate in Q3 FY17 conference call - April 26, 2017.

Editor's comments:- other interesting things which Seagate mentioned in this conference call...
  • the company thinks that only 10% of its current HDD portfolio is feasibly replaceable by flash.
  • Seagate's flash and cloud systems business grew sales 19% yoy.
  • The company's assessment is that its SSD sales could have been maybe upto $50 million higher had it not been for shortages of memory.

lowering cloud wattage with low DWPD SATA SSDs
Editor:- August 4, 2016 - Although it's the faster SSD products (like PCIe SSDs and memory channel SSDs) which capture the attention of readers - because they show what is possible (and after a long enough interval we see pioneering enterprise speeds becoming commonplace at lower prices as we're now seeing with M.2 SSDs) nevertheless - when it comes to where most of the SSD slots are - the workhorse of the SSD market - in arrays, webscale and cloud - is still the simple 2.5" SATA SSD.

disk writes per day in enterprise SSDs
Well, maybe not that simple - because since about 2012 we started to see subtle power optimized and mostly read oriented (low DWPD) SATA SSD product lines being introduced specifically for use in dense populations in the cloud.

It's a big market for SSD vendors and SATA SSDs are a low risk choice for users because there are so many competing companies and products that ensure continuous improvements in value and quality.

Dot Hill acquisition could reposition Seagate as one of the leading standard platforms in the highly competitive legacy enterprise hybrid storage appliance market
Editor:- August 18, 2015 - Seagate today announced it will acquire Dot Hill Systems in an all-cash transaction valued at $9.75 per share, or a total of approximately $694 million.

Editor's comments:- this is a good strategic move for Seagate which now secures an enterprise market proven hybrid storage caching and tiering technology which can be used as a framework for hybrid appliances and cloud infrastructure.

The enterprise software stack and patent IP assets from Dot Hill will enable Seagate to credibly position its SSD caching technologies as second to none in mid range traditional legacy enterprise environments.

Dot Hill's marketing had been foundering around for a few years and the company was seemingly unable to get the kind of market attention it would have got if it were offering the same technology as a startup. Part of the problem was that - as an old time company from the dotcom era - which had relied on 3rd party companies oeming its products - Dot Hill had neglected to develop the same kind of marketing charisma and brand identity as many of the newer companies which it has been competing with.

As part of Seagate - Dot Hill 's caching technology could become a viable alternative platform for integrators who want to compete with newer vendors Tegile, Nimble, NexGen and hybrids from older vendors like HP and EMC.

Seagate's new SSDs
Editor:- May 8, 2013 - "Seagate is Serious about SSD and Flash Technology."

That's the headline of a new SSD products overview page mentioned in a recent press release about 3 of the company's newest SSDs. It's the SAS product which to my way of thinking is the really new thing here.

Until now if you wanted a 1.8" SSD with a SAS interface you had to go to SMART to get one.

The SAS drives market - which Seagate helped to create - used to be seen by external commentators as a strategic market for Seagate. (And no doubt it's still regarded that way by SAS product managers within the company.)

But Seagate's tardy entry into the enterprise SSD market (December 2009) which happened only after many of its own enterprise customers had already responded to the SSD wake up call by making their own arrangements - meant that Seagate's continuing existence as a long term enterprise drive supplier in a world which was rapidly adopting SSDs was called into question.

Then when Seagate's first enterprise SSD dance partners (SandForce and LSI) eloped to re-emerge as rival competitors about a year ago - Seagate was left in such a sorry state that some well meaning stakeholders and seld serving investors were trying to pair the company off in rumor blogs with OCZ or STEC (neither of which were looking for such a hook up).

Instead - as we learned recently - Seagate found a very suitable match in the PCIe SSD market with Virident. And it's safe to assume that if they have any children as a couiple they will look like 2.5" PCIe SSDs.

As to Seagate taking the SSD market seriously - which is where I began this - you could ask - who doesn't?

To misquote Jane Austen - "It is a truth universally acknowledged, that a storage company in possession of a good fortune must be in want of an SSD product line."

On the other hand - I would take Seagate's sentiments about SSDs more seriously if they had been expressed on instead of on the less imposing address where it currently resides -
"...the SSD market will be bigger in revenue than the hard drive market ever was."
How will hard drives fare in an SSD world?
How "solid" is an SSHD? - when less than 2% of the capacity is solid state
Editor:- March 5, 2013 - Seagate would like you to believe that the best way to make a consumer SSD better (more affordable) is to put it in a hard drive.

The company describes this as "SSD + HDD = the best of both worlds."

Seagate's latest offerings at the hybrid drive altar - Seagate SSHDs (Solid State Hybrid Drives) - which are designed to deliver "SSD-like response from your favorite applications and files" are now shipping in 2 main wrapper styles:-
  • Seagate Desktop SSHDs - are similar to the notebook drives and have upto 2TB magnetic capacity in a higher package (26mm rather than 9.5mm).
"Seagate's engineers have really out done themselves this time" said Scott Horn, Seagate's VP of marketing in a press release today.

"Our new SSHDs serve up your favorite content with the lightning-fast performance you have to experience to believe. With these new drives it's like adding a turbo-charge to your PC, without having to sacrifice capacity, at a price that's easy on your wallet. Now consumers can create, store and consume digital content like a pro without having to spend like one."

Editor's comments:- Hybrid drives like this are aimed at the benchmark experience. Seagate says they'll boot 5x faster than a 5,400 RPM HDD based notebook. But will that translate into the kind of product which users will rave about?

Ask yourself this question.... If this kind of flash to HDD caching ratio (125 to 1) works so well - how come the enterprise rackmount storage market isn't dominated by racks stuffed full of Seagate hybrids - using an enterprise-adapted version of Seagate's Adaptive Memory Technology?

What are all the clever people in the enterprise storage market doing wrong? - with their different ways of doing Auto-tuning SSD Accelerated Pools of storage?

That's the question I asked myself about the viability of hybrid drives on these pages back in 2005 - when the hybrid drive market began. And I concluded that - if as a user you want better performance - you will generally get better results and economics by using vanilla HDDs in your HDD+SSD mix.

That doesn't mean to say that millions of people won't buy hybrid based PCs. The question is - would they choose to buy the same product again? And would they recommend it to their friends?

If you really want park bench performance in the PC experience- rather than benchmark experience - here's 2 ways to dissect and improve the Seagate SSHD.
