|SAS SSDs were main reason
for SanDisk's enterprise SSD revenue |
Editor:- April 16, 2014 -
$1.5 billion revenue for the quarter ended March 30.
In a related
Mehrotra, president and CEO stated "...Combined client and
enterprise SSD sales accounted for ($423 million) 28% of our first quarter
revenue, with enterprise SSD revenue more than doubling on a
year-over-year basis. Our expanded SAS SSD portfolio has enabled us to further
strengthen our market position, and it has been the primary contributor to our
enterprise SSD revenue growth."
SAS SSDs - the stellar performers in the 2013 enterprise market
March 20, 2014 - I asked Gregory
Wong, President, Forward Insights
if he could enumerate for StorageSearch.com
readers what he meant by his tantalizing comment that - "within the
enterprise segment, SAS SSDs stood out as the stellar performer" - which is
something he said in a recent email promoting another new SSD market report.
empathetic to the business pressures of those in the
storage market research
business - and keenly aware of the thin line which divides - on the one
hand - saying too little - so that potential buyers find it hard to assess if a
new report will be money well spent - and, on the other hand - saying too
much - and worst of all - revealing the exact things which report buyers
would happily pay to know.
That's because in 1992 when I started
outputs of my own enterprise market research - I did it the hard way - as
carefully formatted market reports which cost money. Luckily there was a much
easier business for me - as I learned in 1996 when I went over to the dark side
of a web advertising
driven business model - in which content and ideas were tossed into the
eco-sphere of http and it was much easier as I could save time by linking to
raw content - instead of having to make it look pretty.
So what I
actually said to Greg - re his SAS SSD "stellar performer"
comparison was this...
"Without giving too much away... would
you be prepared to illustrate that statement with a comparison or number?"
Greg gets a lot of email - and so do I - and sometimes they just disappear deep
down the screen. But between the two of us this one has resurfaced.
I can convey to you Gregory Wong's assessment that in 2013 - the SSD market
grew 38% on unit basis and 28% on revenue basis. The corresponding growth rates
for SAS SSDs were 134% and 69% respectively."

OCZ relaunches as a Toshiba Group company
January 21, 2014 - Toshiba
some details of how OCZ
Storage Solutions (which was based on the recently acquired assets of
OCZ Technology Group) will operate within the Toshiba Group of Companies.
The new OCZ Storage Solutions, under the continuing direction of CEO Ralph Schmitt
- will leverage Toshiba's cutting-edge NAND and combine it with the company's
proprietary controllers, firmware and software to provide both client and
enterprise customers with innovative and cost-effective SSD solutions.
OCZ Storage Solutions will continue to maintain its established
worldwide sales channels. Its headquarters will remain in San Jose, California,
with strategic design centers located in Irvine (California), Tel Aviv (Israel),
and Abingdon (UK).
"The acquisition of OCZ further expands our
solid-state storage capabilities and represents Toshiba's commitment to this
high-growth area," said Seiichi Mori, VP of Toshiba's
Semiconductor and Storage Company. "Our goal is to offer a leading edge
portfolio of solid state solutions to address the storage challenges faced by
both client and enterprise customers, and the acquisition of OCZ is an ideal
addition to our team in realizing this strategy."
provides Toshiba with OCZ's enterprise and client SSD businesses and enables the
established OCZ brand to continue in full force with a current product portfolio
that includes SATA and PCIe consumer drives for high-performance and mainstream
applications, and SATA,
PCIe enterprise drives
supported by virtualization,
cache and acceleration
Editor's comments:- The new OCZ - starts out in a
strong competitive position - as it not only inherits a well established
enterprise SSD business (which I discussed in an
article in November
2013) - but it sheds many of the disadvantages which limited the revenue
scalability of the old OCZ entity in the year leading up to its bankruptcy.
advantages which the new OCZ will benefit from include:-
- less constrained future access to
flash memory for its SSDs
The old OCZ suffered from allocation and cost issues related to its
perceived riskiness as a flash customer.
- strengthening of the
brand was already very strong in the SSD market. But for some customers in
enterprise and embedded markets - there would always be an element of doubt
about the long term roadmaps due to instabilities in the SSD market. Now as
part of the long established Toshiba group of companies - many users will be
happy to temporarily set such concerns aside - and focus more on the individual
merits of particular products and their technical suitability .
- access to more flash
and SSD IP.
acquisition in the
SSD market is different - early indications are that OCZ could become a
launch pad for integrating and expanding some of Toshiba's legacy SSD assets
into bigger markets - especially in the enterprise segments.

conversation with Kaminario's CEO few years ago BTW ) - had acquired a
reputation of being out of reach pricewise - and not just in a class of their

of the ways that Kaminario has pulled off the affordability trick is to drop

another factor is that Fusion-io itself is on course to become a significant

STEC launches 2TB SAS SSD
Editor:- January 28, 2013 -
One of the oddest linking ideas I've ever seen in an SSD news story appeared
today in a
release from STEC
which suggests that anyone should care that the company is the first in the
market to launch both a 2TB PCIe SSD ($9,425) and a 2TB SAS SSD ($7,995).
marketing communication undervalues the true achievement of a 2TB
SAS drive (assuming it
fits in a standard height - unlike a previous model).
lost in this mixed up marketing communication is the idea that STEC is offering
"Unlimited Writes" on some variations of these products. (Which
goal is possible using a variety of different techniques - at the extremes
being slower performance, using more expensive flash or RAM caching - I haven't
asked which of these applies.)

Smart's MLC SAS SSD beats SLC rivals - says StorageReview.com
Editor:- October 10, 2012 - The performance of some leading
SAS SSDs were compared
in a recent
published yesterday in StorageReview.com which compared the latest
technology based MLC drives from Smart Storage
with older SLC SAS SSDs from SanDisk, HGST and Toshiba.
review said Smart's Optimus was the performance leader in nearly all tests,
although there was one serious blip and performance outage which looks to me
like it may require a firmware fix.
A serious flaw in this review
was, however, the absence of any modern MLC products from
that the performance comparisons of these 6Gbps drives does convincingly
demonstrate that overall enterprise SSD design is more important than raw
memory type (one of the tenets in the
SSD survivor's guide).
How important is this review? Anyone who's
already shipping boxes populated with merchant market SAS SSDs will already
be aware of the potential suppliers - but it might give them another reason to
look at Smart to prune their costs. But when it comes to performance? - I'm not
so sure it's useful - as 12Gbps SAS SSDs have already having been demonstrated
by several vendors in prototype form earlier this year and that's the
direction oems will be looking at for ultimate SAS performance in the
future... Apart from those who are thinking about switching to
2.5" PCIe SSDs.
A month later - StorageReview.com did publish a
of STEC's MLC SAS SSD - the s840. In this comparison Smart beats STEC on
peak performance - but STEC's performance is more consistent. However, STEC's
SSD doesn't fit into the same low profile space.

integrity) for the SLC model are 1 in 1016 . Seagate also
quotes a permissive rate of ambient temperature change for its MLC SSD - which
is something else we may be hearing more about in future.
comments:- one of the problems Seagate has in being a latecomer to the SSD
market is that it hasn't yet racked up enough "million customer operating
years" to support reliability messages tagged to the new SSD launch. So
instead it's using cross over references from its HDD business - as in this
statement - "Over 200 man-years of development went into the
2nd-generation Pulsar SSD products, with enterprise reliability verified by a
team with over 1,500 collective years of experience in the storage industry."
history in recent years teaches us that experience in other markets
(even within the semiconductor industry) doesn't always guarantee that new
SSD designs will be as reliable,
trouble free or as
fast as their
creators anticipate. That's because many new design features in flash SSD
architectures get their first reality checks in the market. I expect that if
all goes well - next year Seagate's new SSD announcements will start referring
back to their SSD market track record. And if all doesn't go well - we're hear
about it on these news pages.

oems only sell their SAS SSDs for use within their own rackmount storage
The SAS SSD market was slow to get started compared to other
segments in the enterprise SSD market and
it was overshadowed by 3 related competitors within the SSD market
itself - which took away business.
- fibre-channel SSDs
- which started long before SAS SSDs - (the first rackmount FC SAN SSDs
shipped in the late 1990s - and
3.5" FC SSDs were
shipping more than 5 years before the first SAS SSDs).
- SATA SSDs -
which started just immediately before SAS SSDs and dampened the early years
of demand for SAS SSDs
mentioned above the SAS SSD market was the slowest part of the SSD market to
take off - in the post "SSD awareness" era. For many years there were
only 1 or 2 vendors in the market - and
STEC in particular
benefited from its surprising position as being almost a monopoly supplier of
SAS SSD drive that worked and passed the oem tick tests. But those days are long
gone - and the market dynamics are more complex today with more choices in
suppliers and performance.
- PCIe SSDs which
started later than the SAS SSD market but creamed off most of the market for
what would have been high end SAS SSDs - if PCIe SSDs hadn't existed.
if that wasn't enough - a new threat for SAS SSD slots inside server racks has
been emerging in
the past year with removable
2.5" PCIe SSDs.
As the editor of StorageSearch.com I was
actively reporting on - and our readers were actively influencing - the growth
of both SSDs and the SAS market.
Here's the timeline from the birth of
SAS to the preliminary phases of the SAS SSD market.
the birth of Serial Attached SCSI (SAS) storageNovember 2001 -
leading vendors announced they would collaborate to set up a working group
to develop and co-ordinate a new interface standard which would be called "Serial

SSD buyers survey
showed SAS SSDs as the 8th most desirable SSD interface to meet buyers' future
needs. (No SAS SSDs were available in the market at that time.)
