solid state disks with
multi gigabyte per second sustained throughput have been around since
as datacenter acceleration rackmounts. The best known example being the
Texas Memory Systems.
Despite the high price tag of such systems ($1 million in 2003 and
still somewhat North of $100K) many enterprises have been delighted to
discover that these products have offered enterprise wide application speedups
across hundreds of servers - at a much lower cost than traditional disk based
storage arrays - as published in numerous
has been nice for the rest of us mere mortals (and that includes mouse mortals
not just the human variety) to learn about such products, but just as most of
us don't have our own personal jet, the ultra fast Terabyte SSD has not been a
technology that has affected our everyday lives.
But that will change,
a lot sooner than you may think.

flash SSD. It will
initially cost over $10,000 - but will be on a steeply declining
semiconductor cost curve - and may drop to as little as $1,000 by 2012.
prediction is solidly based on extrapolating 2 separate announcements from
MOSAID. In case you
missed them, here's a summary.
April 2007 - STEC, Inc announced a 512GB solid state drive
aimed at video-on-demand services.
"STEC believes that
solid-state Flash drives with high-IOPS performance will address the growing
needs of the enterprise-class drive market. With NAND Flash prices declining on
a continued rapid pace, prices for
SSDs are expected to drop
below $2 per GB by 2012 which implies 512GB of high-performance storage for less
than $1,000. Based upon these capacity and pricing dynamics, STEC expects that
the high-IOPS SSD will make up a significant percentage of the $5 billion
market. This will make the comparative performance gains of SSD over HDD even

Although this device (made by
Curtis) is a
RAM based SSD it points
to the fact that even in the current state of the market the conventional
hard disk interfaces
such as SATA (which
are not stretched by rotating magnetic film technology) will have to get a move
on if they are to keep up with the bandwidth demands of high end SSDs.
Now's the time to start planning what you will do with the future
generation of ultrafast flash SSDs. It's going to change what species live in
the server farm.
