IO Turbine gets funding for flash SSD IOPSware
Editor:- April 19, 2011 - IO Turbine is a new
(to me) storage software
company which is designing software for
virtual flash SSD environments.
The company popped out of stealth

Lightspeed Venture Partners, as well as Merus Capital and notable angel

areas as system software development and virtualization," said Manouch
Moshayedi, Chairman and CEO of STEC. "As the overall trend of hardware and
software convergence in the storage industry continues, it is important for us
to expand our product portfolio by creating increasingly intelligent storage
solutions that accelerate the adoption of solid-state drives in enterprise
servers. Establishing a presence in India provides us with strategic access to a
global software hub with a pool of top engineering talent to cost-effectively
meet our R&D expansion plans."

Samsung exits shrinking HDD market
Editor:- April 19, 2011 - One alternative way of looking at Seagate is as one of
the world's leading storage
market analysts - when it comes to the subject of
this unsung role Seagate today published
report (pdf) - which among other things includes this useful total market
size info - related to the most recent quarter.
that its revenue had declined 11% year on year and that it has entered
into an agreement to buy Samsung's
HDD business for $1.375 billion.
- enterprise HDD market - 13.8 million units - (up 10% year on year)
- client HDD market - 115 million units - (down 7% year on year)
Samsung will supply NAND flash
to Seagate's SSD products (no surprise there as Samsung is a strategic
supplier to countless SSD companies already) and Seagate will supply hard
drives for Samsung's PCs and notebooks (no surprise there either as Samsung was
probably the biggest customer of its own HDDs).
Exiting the hard drive
business is a no-brainer for Samsung who within the next 5 - 9 years must
transition its entire memory business over to SSDs when the SSD market is big
I'm not sentimental about the end of hard drives - having
written enough articles about that subject already.

"The March quarter in the hard drive industry was
impacted by 2 significant developments - the delayed supply of industry CPUs to
PC makers and the tragic events in Japan," said John Coyne, president and
CEO. "While demand for hard drives in the quarter got off to a slow start,
it later picked up as availability of CPUs improved and as fears took hold of
component shortages related to the events in Japan."
TMS announces 15% price drop in flagship SLC SSD
April 19, 2011 - Texas
Memory Systems today announced that new customers of its flagship
RamSan-630 (a fast
will be the
first enterprise SSD users to benefit from the performance improvements and
greater cost efficiencies provided by a new generation of
SLC flash memory chips designed by Toshiba.
Memory Systems continually evaluates all major
flash memory suppliers'
product offerings to determine the 'best of breed'," said
CTO at Texas Memory Systems. "The significant engineering effort put forth
to validate the devices is essential in order to guarantee our users receive the
best quality and performance from the RamSan."
The result is a
15% lowering of the system price. New pricing starts at $50K list.
comments:- in an interview
last December TMS explained why it was sticking with
SLC rather than
MLC for the foreseeable future. And in another interview (January 2011)
which revealed performance
boosting features inside the RamSan-630 I learned that out of the many
(double digits) of SSD product generations which the company had designed
this particular family included many hallmarks of a classic product.
Today's announcement is an indication that the RamSan-630 is going to stay
around for some time.
$50k is a magic door opener for high end
mission critical enterprise SSDs. That's something which
Dani Golan told
me recently when they launched their K2 (a competitor to Texas Memory Systems's
RAM SSD product line). Both companies say that in addition to the traditional
large enterprises who have always bought SSDs - they're now getting business
from small new companies in the pure internet economy.
New update to Top 20 SSD Companies List
April 18, 2011 - today I added a new footnote to the recently published
edition (Q1 2011)
of the top 20 SSD
companies list - which answers a question I've often been asked by
marketers in SSD companies during the 4+ years that this series has been
running - "how much difference does advertising make to these lists?"
you work in sales or marketing you won't be interested in reading the new
details - because whether I include or exclude advertising data I still get
exactly the same companies in the top 10 list - just ranked in a slightly
