|STEC samples Extreme Endurance SAS MLC SSDs
Editor:- November 29, 2011 - STEC has started
sampling a new
MLC SSD - based on its proprietary
- the new ZeusIOPS
XE (Extreme Endurance) is a 6Gbps SAS SSD family, available in
3.5" sizes (300GB
or 600GB) and supports at least 30 full capacity writes per day, every day,
for 5 years.
Latency is upto 50 microseconds. Sustained R/W throughput
is upto 500MB/s and 275MB/s respectively and random IOPS is upto 38,000 8K
(70R/30W). STEC says the new SSDs (based on 32nm MLC) are suited for
write-intensive applications with the high endurance necessary to support
auto-tiering, metadata management and logging, and analytics.
OCZ samples terabyte dual port 6Gbps 2.5" SAS SSDs
November 29, 2011 - OCZ

Editor's comments:- which of these 2 new SAS SSDs announced
today will be better for you? - The ZeusIOPS XE (from STEC) or the Talos 2
One thing's for sure - you can't just decide from looking
at the press releases.
Price is a very
important factor too - particularly if your app involves heavy duty caching -
you may decide that to get the same
end up comparing an MLC SSD managed by CellCare (the STEC offer) to an eMLC
(or even SLC) SSD managed by DuraClass (the OCZ offer).
Or based on
your past experience with these suppliers you may apply your own
adjustment factor to their price projections and reliability projections.
Or based on who you are - you may not score highly enough to
get your hands on early evaluation samples at all.
And that's before
you even start looking at what
SanDisk might do with
their Lightning or what
WD might do with
the Ultrastar when they get it from Hitachi GST.
One consolation may
be that there are less controllers
to choose from in the SAS market than when you look at

BiTMICRO unveils Big SSD Architecture - ASIC platform
November 21, 2011 - BiTMICRO
that it has designed a new generation of enterprise
SSD controllers which
will deliver upto 400,000
support upto 5TB capacity and will be available in SSDs with
Fibre Channel, and
PCIe interfaces in the
first half of 2012.
BiTMICRO's new ASIC based platform architecture consists of a
multi-core SSD controller integrated with multiple high-speed serial on-chip
buses and embedded processors
"It is with high anticipation that
we see these technologies come to fruition and work for our customers",
said BiTMICRO's CEO, Rey Bruce.
Editor's comments:- 4
years ago (2007)
BiTMICRO was at the top of its game (and
#1 in the top SSD
companies list) with an industry leading terabyte class
3.5" FC SSD
sampling (called the E-Disk
Altima ) but the company got hit from about 50 different directions by newer
flash SSD companies which grabbed many of the sub-markets which previously had
been divided up among a handful of enterprise vendors.
Having a 2 stage
SSD controller architecture - with a core intelligent unit - which fans out to
distributed flash slave teams is a proven architectural feature in high
performance enterprise SSDs.
For example it's used in products by
(whose controller can keep 256 flash die active concurrently on R/W garbage
collection etc) and also by
Texas Memory Systems
(whose controller can
bundle up multiple
FC channels into a single virtual route into the flash array). These are
examples of what I call
architecture - which is more efficient (higher percentage of usable
capacity), faster and more
reliable in large
capacity SSD products than arrays of small architecture SSDs.
how can all these SSD companies keep growing?
November 21, 2011 - I'm often asked this question...

today I've published a new article - which summarizes what I've been saying to
the readers I talk to. But I've redacted the actual company names from [list] -
because everyone's got their own little list of SSD companies for which my
answer may hold true. ...click to read

SSDs in TV
Editor:- November 21, 2011 - An
article in TVTechnology.com
discusses the state of play for SSDs in the tv industry.
one of the statements in the article - about the readiness of SSDs for the
enterprise market is
incorrect in suggesting that
consumer SSDs came
first. I'd like to know which consumers were spending $40K for an entry level
SSD back in the 1990s? Nevertheless the article shows what some people in the
tv equipment market are thinking. See also:-

now sticky SSD cards can chew rack-size data
November 15, 2011 - Fusion-io
that it will ship 10TB versions of its
(so-called because it includes 8 memory modules on double-wide
PCIe cards) in the
next quarter - which deliver 1.3 million IOPS with 6.7 GB/s bandwidth.
means up to 20TB of bus accessible flash-based acceleration in a 1U server and
40TB (using 4 Octal drives) in a 4U server, such as the HP ProLiant DL585 G7.
Editor's comments:- While keeping in mind that recently
unveiled "future" products always look glossy compared to what's
already been shipping - how does the new Octal capacity compare to current
products from other SSD makers?
Compared to other fast
PCIe SSDs - it's
nearly double the density of the
R4 R from OCZ.
to fast FC SAN
SSDs - the capacity density leaders are the
(10TB in 1U) - from Texas
Memory Systems and the
(22TB in 3U) - from Violin
Memory. However, in the case of these rackmounts the capacities quoted are
rather than "raw" (about 30% more flash inside is below the level
So Fusion-io's new Octal will enable systems integrators to
meet or exceed the storage density of leading rackmount SSDs while still having
the application flexibility offered by being resident in industry standard
Fusion-io's CMO, Rick White spoke to me
about the new market opportunities it will open up for FIO's partners -
particularly when they
APIs (aka "Virtual Storage Layer"). He said that having 20TB to
40TB of low latency SSD in a single server fitted well with many data
warehouse applications for example.
In a recent article I discussed
the market interplay
of PCIe SSDs and rackmount SAN SSDs and picked up on the theme of "data
decentralization" which Fusion-io had started to talk about recently. When
I asked Rick about decentralization he said it was more accurate to think about
it as "shared decentralization" because whereas the data wasn't
sitting on a SAN - being
inside a server meant it was also accessible to any other servers that could
talk to this one.
I asked about
price - and while
(understandably) not wanting to be too definitive (because the price depends on
who you are, when you buy, and where you are in the channel, etc) - Rick said
in effect that the PCIe SSD market is very competitive - and that all new
products have to look attractive compared to what they are supposed to replace
and he referred me to price guidance the company had given in a recent
investors conference call.
"Stickiness" is another thing we
talked about. I've been saying for a long time that once a customer starts using
FIO's APIs to optimize performance (by xN - where N can be any number from 2 to
10) it means that competing PCIe SSDs look less attractive - even if they have
spot performance specs which are faster. Rick agreed that this assessment is
correct - and reminded me that several years ago he had described Fusion-io to
me as a "software company". From the business point of view it's good
for Fusion-io's business - but also good for FIO's business partners - because
as the catalog of VSL
compatible APIs and applets grows - they can get more powerful functionality for
lower incremental development cost.
So what can you do with an Octal
powered server that you couldn't do before?
One trivial example is
that if you add some dedupe,
compression and an iSCSI
stack you can easily create a 1U storage appliance with maybe 100TB to 200TB
of fast virtual storage which (because of the low latency) will run rings
around similar bulk storage SSDs which use
2.5" SSDs in
general availability of denser PCIe SSDs - which we'll see across the whole
market next year -
means that servers will grow up to be faster a lot sooner than they have been
doing in the past decade. And having 10x faster servers always creates
new markets which weren't viable before.

Editor's comments:- Virident today
updated its website to include a host of new customer endorsements and
performance data. The company's positioning is that it aims to provide
consistent enterprise performance (relative to the variables of block size,
how full the SSD is etc) rather than a product which has speed spikes which
vary across dimensions and time. (Attacking older models from

delivers it too. Achieving balanced spike-free acceleration in
flash SSDs is done at the
design stage from an optimal mix of
big vs small
vs fat cache,
optimizing the RAID for flash
(for performance and reliability), using fast
integration with SSD
What will the company do with the new
funding? - In the current
SSD market bubble
all PCIe SSD vendors are trying to establish design wins by technical
superiority and market share by revenue growth - but making a profit isn't a
realistic prospect for most of them. So the money will be used to pay
salaries and suppliers and keep the show on the road until the next review
point - which in Virident's case could be another round of funding, IPO, or -
more likely in my view - getting acquired.

performance of up to 245,000
R/W rates upto 1,900MB/s and 1,725MBs/ respectively. Power consumption is
13.5W idle, 14.3W active.
Editor's comments:- these aren't
OCZ's fastest SSDs, and I couldn't find a clear explanation on their site how
the new products were positioned relative to the pre-existing

STEC still fails to benefit from growing SSD market
November 8, 2011 - As expected - STEC's revenue slope is
still pointing in the wrong direction.
revenue for the 3rd quarter of 2011 was $72.5 million, a decrease of 15%
from the year ago quarter.
Editor's comments:- it will be
several more quarters before it becomes clear whether STEC's currently
qualifying products will be market hits or not. That's why I wrote in August -
"STEC is now cheap to buy - but would be very expensive to own..."
As previously discussed the company's marketing response to changes in the
enterprise SSD market in recent years has been inadequate in 3 main areas.
- STEC needed to develop more diverse routes to market. The growing size of
the market and customer opportunities couldn't be matched with its outdated oem
business model. More enterprise sales channels would do more than grow STEC's
revenue. They would grow its market intelligence too.
example because there were no STEC branded
the company was several steps removed from learning what enterprise SSD end
users really wanted.
- STEC was naive in thinking that FUD factors related to quality problems
with some wannabe SSD competitors a few years ago (such as
Intel) would provide more
than a temporary respite from competitive pressure coming from
market weeded out which suppliers it could trust and has accepted competing
SSD technologies in the high IOPS space.
There's a funny scene in the movie -
The Dish - when the
Australian relay station has lost contact with Apollo 11 and the scientists
debate the science behind exactly where to point the microwave dish based on
its last known position, spin of the Earth etc. Someone looks out the window,
sees the moon and says - point it there!
- STEC completely failed to react adequately (for years) to the seismic
market shift in the enterprise market opened up by
PCIe SSDs which were
being led by Fusion-io.
In the SSD market context - "there"
If STEC can come up with a good story that
satisfies the editor and readers of StorageSearch.com they have a credible
place in the SSD business map of the future then STEC's revenue slope might
spin around to align in a more positive direction.

(which) SSD Makers Benefit From Thailand Flood ?
November 4, 2011 - a
on SeekingAlpha.com written by Dana Blankenhorn - discusses
which SSD makers could benefit in the short term from HDD shortages.
comments:- In my view Dana Blankenhorn is correct to suggest it will be
small form factor / notebook SSD makers.
3 weeks ago - when WD and
Seagate alerted the market to this potential supply problems in
hard disks - I said -
something along the lines of - "let them eat cake" - referring to
oems who may have to use SSDs instead.
I doubt whether the volume of
SSDs that switch sooner into HDD slots will make a big difference to any SSD
maker's profit in the next few months - but it could increase the urgency of
some SSD qualification programs.
The big market for
SSDs in 2012 will be
in the enterprise - where the shortage of HDDs will make absolutely no
difference - because HDDs were already on the hit list.

of $74 million for the quarter ended September 30 - nearly 3x higher
than the year ago quarter.
But the company is offering guidance that
its revenue growth for the whole of FY2012 may be closer to 55%.
comments:- It's difficult for any
analyst to make a
reliable prediction about FIO's revenue growth - because that involves
guessing the relative competitiveness of future products which aren't in
the public domain - and prejudging relative marketing outcomes against
competing companies who may not be currently on the radar.
the past - FIO has executed extraordinarily well. And looking ahead - their
technology is competitively scalable - and a good fit into any business upside
that could arise from closely integrating
SSD software with
PCIe SSDs - because
their APIs have almost zero-latency access into the flash management layer. This
is what I call being inside the SSD controller loop (rather than poking
from the outside). There are advantages and disadvantages in both approaches.
How will the overall PCIe SSD market grow? - My guess is will more
than double in revenue next year - but the market spoils will be divvied up
among even more competitors. Despite that I think that so long as FIO
doesn't shoot itself in the foot (with a product or production glitch)
its customers, partners and investors should remain happy. I expect there will
be plenty of happiness to go around for other enterprise SSD makers too.
RunCore is one of China's fastest growing tech companies

still in the top 10 in the
current edition .
Competition to get into the top 10 SSD companies list is getting harder for
all companies - as the number of SSD companies has risen from 112 to over 300
in the meantime. But when a company is in 2 lists like this - it shows that
customers think they're doing a lot of things right.

an attractive acquisition prospect right now - because despite having unique
SSD IP, a great
reputation for reliability
and a strong brand
(everyone knows they can't afford STEC - or thinks they can't) - it's not been
clear where the next 2 -3 quarters of enterprise SSD revenue growth will be
coming from - if their biggest customer starts fooling around with other SSD
partners (and maybe it wasn't really
legal marriage - because it was on a beach).
But if STEC does
succeed in setting up more diverse routes to market - and behaves like a
sales company that's interested in new customers -
2012 will be the best year
history to test out those new business models.

- SSD market
analysts - StorageSearch.com is a trusted primary resource in the SSD
market - but the more you learn about this market - the more questions you
realize remain unanswered (or unanswerable). I compiled this filtered list
as a recommended resource for all those people who need custom reports and
detailed market help - which go way beyond my limited "content
prioritized" time budget or would involve too many conflicts of
interest for me to take on.
- SSD jargon -
because we've have been at the leading edge of reporting the SSD market -
we've had to invent some of the jargon which is used to describe some SSD
concepts. You can't have a meaningful discussion about the intricacies of SSD
design without using these words. This article gives you simple explanations of
these terms and tells you where they came from - and links you to more detailed
info if needed.
SSDs - market overview.
- 3.5" SSDs

performance specs which sound impressive now! (As long as you don't mention the
- SSD Data Recovery
- this is the industry's first SSD recovery directory (a topic we started
writing about in 2007).
It includes articles and news related to recovering data from faulty or
SSD sudden power loss - this article surveys SSD power down management
across all the SSD architecture types in the market today. It explains why
subtle design choices made to boost speed can have drastic conseqences in
flexibility of system deployment. Power cycling induced faults kill more
SSDs in real life than endurance ever did. But SSD PSU management topology is
rarely mentioned in most SSD datasheets.
- the problem
with Write IOPS in flash SSDs - this classic article helps you understand
why a once well regarded performance modelling metric (IOPS) got abused - and
why all SSD benchmarks incorrectly suggest you're going to get much higher
performance from some types of flash SSDs than you will actually see in your

Performance Roadmap (Z's laws) - published in 2008 included performance and
architectural roadmaps and projections till 2012. Most were very accurate when
viewed with the benefit of hindsight - although one (re IOPS symmetry) was not.
For several years I added updates to show what has happening compared to the
predictions. Except for those interested in historical research this article has
been mostly superceded by newer content.

looking at Enterprise SSDs - published in September 2010. This is a
unique new segmentation method which cuts across interface and form factor to
provide a simpler way for customers to categorize products into the "learn
more" or "ignore" mental buckets. Industry leaders I've spoken to
since the article was published have told me they like the simplicity of the
new terminology - whichever side of the line their own companies happen to be
