IRVINE, California, October 28 /PRNewswire/ --

Hagiwara Sys-Com Co., Ltd. -- the industry leader in semiconductor
application products for industrial/embedded computing -- today announced new
additions to its TRUESSD(R) product family: The DFD series for mission
critical applications and the SFD series for enterprise applications.

These new models were developed based on the well-received "TRUESSD(R)
HFD series" that offers high data reliability and outstanding drive
endurance.

The DFD series targets mission critical applications by adding support
for specific requirements in the market segment such as a hardware trigger
jumper to attach a physical switch for hardware-initiated secure erase.

SFD series targets enterprise storage / server applications. The enhanced
DRAM cache provides a 50% increase in read/write performance, 95MB/ sec and
60MB/sec. respectively, in comparison to the base model.

Both series are built with 100% pre-screened single level cell NAND flash
components in 2.5-inch form factor SATA interface.

The continuous shrinking geometry of NAND flash impacts overall
reliability. The two specific areas impacted are increased raw bit error and
decreased program-erase cycles. The TRUESSD(R) flash controller, used in the
HFD/SFD/DFD series, is designed to minimize these impacts in an effort to
provide the same level of reliability that previous NAND generation products
have been able to achieve.

The TRUESSD(R) possesses multi-channel flash access and provides 8-bit
ECC On-The-Fly for each flash channel to address the increasing raw bit error
of NAND flash.

One cause of the increasing raw bit error is induced by very high number
of read access to a specific page within the NAND flash, known as Read
Disturb. The TRUESSD(R) controller takes a proactive approach to prevent this
error from occurring by monitoring read cycles and performing "Refresh", a
re-write cycle, on potentially affected memory blocks.

NAND flash has a finite program erase cycle and this number is declining
as geometry shrink progresses. The TRUESSD(R) controller performs static
wear-leveling that distributes write operations evenly over the entire media
to maximize drive longevity and an intelligent cache algorithm reduces the
number of write access to the NAND flash by organizing smaller fragmented
data into larger data blocks.

The TRUESSD(R) controller also offers a wear indicator LED for on-site
device monitoring that signals the number of remaining replacement blocks of
the device as well as S.M.A.R.T. commands for remote monitoring that can
provide additional information of the device condition.

"Merely designing a fast solid state drive was not our focus. Hagiwara
placed a high priority on data integrity and drive longevity. The result was
the TRUESSD(R) controller," said Moto Watanabe, US Product Manager.

"In response to the many clients requesting for certain features to be
added to the currently released HFD series, we came to the decision of
releasing the DFD for mission critical applications and the SFD for
enterprise server applications where downtime is not an option."
