August 2007 - TDK announced a joint venture
PQI to research, develop
and market Disk on Module (DOM) and
Solid State Disks (SSDs).
In May 2009 - TDK
launched a range of
2.5" industrial temperature SATA SSDs (SLC and MLC) with upto 64GB
capacity and R/W speeds of 95MB/s and 55MB/s respectively. Other features
include 15-bit/sector ECC, 128-bit AES encryption and SMART. The new SSDs
include internal UPS and an auto-recovery function that automatically recovers
data when read disturbance errors occur. The company also launched a range of
In March 2010 -
SHG2A series of half slim, encrypted industrial
SATA SLC SSD modules
with upto 32GB capacity and R/W speeds of 95MB/s and of 55MB/s
respectively. ECC is 8 bit/sector (512 byte) correction (15 bit/sector
is 100,000 write cycles per block address (6.3 billion writes for a 16GB model).
TDK has a life span assessment tool which enables customers to monitor the
life span of these SSDs in their systems.
In March 2012 -
imminent shipments of a new SATA SLC
SSD on chip. The
company's eSSD series provides 1 to 4GB encrypted capacity in a 17mm x 17mm
208-ball BGA package.
|fast erase / purge MIL SSDs|
|The need for fast and
secure data erase - in which vital parts of a flash SSD or its data are
destroyed in seconds - has always been a requirement in military projects.
many industrial SSD
vendors offer products with extended "rugged" operating
environment capabilities - and even notebooks SSDs come with encryption -
it's the availability of fast destructive data purge which differentiates "truly
secure" SSDs which can be deployed in sensitive applications.

By that I mean how big was the mental map? - not how many
inches wide is the SSD.
The novel and the short story both have their
place in literature and the pages look exactly the same. But you know from
experience which works best in different situations and why.
it comes to SSDs - Big versus Small SSD architecture - is something which was
