Editor's comments:- one simple way of looking at
the SF-2000 would be as an incremental x2 version of what SandForce has
done before - which also demonstrates that the glass ceiling for their
architecture is much higher than some people might have thought.
briefing yesterday I learned a lot more about the new chip and got answers from
SandForce to a bunch of technology and marketing questions. I'll post these in
more detail in a special article on the

Samsung supplies 3.5" SATA SSDs to EMC
October 7, 2010 - Samsung
said today it's shipping 200GB
3.5" SATA SLC
SSDs to EMC.
R/W speeds are 260MB/s and 245MB/s respectively. R/W
47,000 and 29,000. The new Samsung SSDs have an 'end-to-end
function and encryption.
worldwide SSD units and revenues for
application will grow to 6.3 million units and $3.6 billion in 2014.
comments:- in a classic article (2004) -
the Datacenter - Steve Gardner
(who was Director, Product Marketing at
Engenio) laid to
rest user fears that SATA hard
drives weren't good enough to use in enterprise apps.
Today as we
know all too well
there's a much bigger spread of characteristics (good and bad) in
SATA SSDs. Pick the
right product and you're delighted. Pick the wrong one and

users are offered plenty of clues about the type of

interpret them correctly is another matter. Although EMC is a follower - rather
than a leader of SSD technologies - the company's reputation for paying strict
attention to reliability
issues means this is a good endorsement for Samsung's enterprise SSDs. Only time
will tell if this confidence was well placed.

SSD battle of the form factors - update
October 3, 2010 - in September (for the 12th straight month in a row)
PCIe SSDs maintained
their lead over 2.5"
SSDs in the battle of the form factors for supremacy in the
server acceleration market - with 48% higher search volume by
readers of StorageSearch.com.
most end-users have purchased their
rackmounts rather than as modules and the ratio of SSD readers searching
for SSD rackmounts has not changed in the past year. But the search data
points towards a shift in the
inside those racks within the segment I call "open" (implemented
by arrays of COTS SSDs) with a bigger slice going to arrays of PCIe SSDs.
To put it crudely - when it comes to vanilla open rackmount
accelerator SSDs (as opposed to application specific or proprietary rackmount
SSDs) the market will lean more towards SSD boxes with
inside than STEC (2.5"
But at sometime in the next several years I expect
2.5" SSDs to once again become the #1 form factor for server
acceleration SSDs. This reordering will come from the need to simplify the
replacement of faulty SSD modules (they may be more
HDDs but they will
still fail) combined with the standardization of PCIe connection in a
SAS form factor - like
we're seeing now in some 3.5" SSD products from
OCZ) - and the emergence of
a new market for bulk storage
backup SSDs. (See also
2.5" NVMe SSDs.)
