|Foremay describes secure

Options for SSDs (pdf) - at the recent Flash Memory Summit.
paper describes the need for
SSD data purge and
the 3 techniques which the company supports in its Avalanche Secure Erase
"In a regular
SSD, deleting a file only
removes its name from the directory or file table. User data remains until
overwritten by new data. Even reformatting the SSD leaves data intact,"
said Jack Winters, CTO of Foremay, during the Flash Security workshop. "The
Avalanche Secure Erase Suite employs various technologies to overwrite or
destroy all user data in allocated blocks and file tables, as well as data in
reallocated defective blocks."
Editor's comments:- other hardware data
destruction technologies for SSDs are also available from

ACARD's new disk duplicators
Editor:- August 17,
2010 - ACARD Technology
new models of 3 way and 5 way SATA
data transfer rate for single
HDD is as high as
6GB/min, so when copying 1TB of data only takes less than 3 hours (The actual
speed varies according to the hard drive). SATA hard drives can support the
1.5Gbps, 3Gbps and 6Gbps specifications, and supports various commonly used hard
drive formats such as Windows, Linux and MacOS.
ACS8503H / ACS8505M is easy to operate, and the hard drive insertion
utilizes the no-screw design. After the tray is opened just insert the source
and target hard drives and press the start button to execute; there are no need
for tools. The LCD displays the progress and status, the hard drive status is
easy to read, the user does not require any professional knowledge and can learn
how to operate it in a very short time.
The supported HPA (Hidden Protected Area) function can fully backup
the data stored in the hidden protected segments of the hard drive.
SMART samples 400GB 2.5" SAS eMLC SSD

SAS SSD - a 2.5" 400GB eMLC SSD with 26,000 / 20,000 R/W
250/230 MB/s sustained throughput.
The new XceedIOPS SAS SSD offers
high reliability and data integrity due to extensive error-correction and
detection capabilities, multi-level data-path and code protection, data-fail
recovery, and data-integrity monitoring. Designed to minimize power surges in
SSD arrays the the XceedIOPS SAS SSD supports staggered power-on.

Since Dataplex works with off-the-shelf storage devices, PC OEMs and
consumers have complete freedom to choose any SSD and any HDD, from any vendor.
"Consumers love the idea of SSD performance, but there is still a
huge (price) gap
between HDDs at $0.20/GB and SSDs at $2.00/GB; as an HDD replacement, the
economics simply don't work for all but a very small percentage of the market,"
said David Lin, VP of product management at NVELO. "With Dataplex, we are
making SSD performance economically feasible for a much larger market by using
the strengths of SSD and HDD technology together. And we're not talking about
simply installing the OS and whatever applications can fit onto a small SSD.
Dataplex learns user behavior, and intelligently caches all important data and
applications in an SSD device while maintaining the full capacity of the HDD for
Dataplex will begin shipping from select Tier 1 PC OEMs
in 2011. NVELO is currently in discussions with leading
SSD vendors to enable
aftermarket sales and bundling options for Dataplex, and has begun development
of an enterprise version of Dataplex for server systems.

Caulkins, Chief Technologist Dataram.
year ago Dataram was at the forefront of a wave of companies creating a new
market for what I called "SSD ASAPs". It's
still unclear which type of approach will be most successful in this emerging
market. But you can learn about the issues that impinge on Dataram's technology
