(at one time) the fastest 2.5" SATA 2.0 flash SSD. The Platinum SSD is
compatible with any OS that supports SATA and appears just like a regular hard
drive but with 40,000 random IOPS performance. It has orders of magnitude
better endurance than pure flash SSDs due to the write attenuation (opposite of
write amplication) which results from its large non volatile internal gigabyte
RAM cache.. Using the Platinum SSD from DTS, you can improve the performance of
many server applications significantly compared to using most other flash
SSDs. DTS was founded in 1996 and has facilities in Japan, US and Pakistan.

DTS made a dramatic entry
into the high performance hard disk market in
2008 with its
Platinum HDD - a 3.5"
which integrated a hard
drive with an internal Gigabyte RAM cache. In 2009 the company used a
similar architecture to launch a 2.5"
fat flash SSD
- in which the bulk store was implemented by a conventional
flash SSD with an

controller transparently managing the performance boost from the fat cache. This
made it the fastest 2.5" drive (rated by
But in 2010 - SSD
controller enhancements from companies like
Anobit made it possible
for 2.5" SSD oems
to get similar / better IOPS performance from flash SSDs using a
architecture without needing an additional external controller and memory.
These competing products had lower parts counts. lower power consumption, better
lower cost - and therefore killed most of the market prospects for the
It remains to be seen whether the SSD market has a nuche for a
"super fat" 2.5" SSD - or in effect a 2.5"
RAM SSD. 3
manufacturers currently ship
3.5" RAM SSDs for
critical database speedups in which the high cost (compared to the
cost of flash SSDs)
is worthwhile - for lucky enterprise users who can relocate the bulk of their
hotspots into 4 to 8GB.
|In February 2009 -
availability of the fastest 3.5"
SATA SSD - the
Platinum HDD 2009 model. Internally it has a 1GB
RAM SSD which operates
as a non volatile RAM cache for an internal
flash SSD (320GB
to 512GB). Aimed at server acceleration applications performance is 25,000 R/W
IOPS, read speed is 250MB/s, and write speed is upto 240MB/s. DTS says the huge
nv cache also attenuates writes (opposite of write amplification) - thereby
wear by x10 to x400 compared to conventional flash SSDs.|
2009 - DTS won
of show award at Interop
Tokyo 2009 for its Platinum SSD. The company says it will ship a
2.5" version of this product -
which delivers about
40,000 IOPS and 250MB/s R/W - later this month.
