For most of

changed. And we're now seeing some worthy and reliable products appearing in
the humble USB form factor - using modern

kind of improvement into smaller, low power SSDs such as SD/MMC and USB which
don't have the same kind of budgets for DRAM and CPU power as enterprise SSDs.

RunCore's video - phone to purge USB SSD
May 22, 2012 - sometimes if I'm watching a movie I realize it's going to be

Editor:- July 9,
Old PCs with SSDs is a cautionary tale published on Denali Software's blog.
I've often told readers who asked me about this subject - that they
could be wasting their time trying to upgrade old notebooks with
SATA SSDs - because
most of the speedup benefits - if any - will be lost by the latency damping
effects of cheap and slow bridge
chips on the motherboard - and that - unlike in a server - notebooks have
precious little CPU headroom.

The USB is now widely used in Macs, PC's and even Linux
systems. USB is typically used to connect devices such as printers, scanners,
keyboards, digital cameras, MP3 players and external storage devices.
June 2002, Intel and others started to demonstrate
USB 2.0, which increases the speed of the peripheral to PC connection
from 12 megabits per second (Mbps) on USB 1.1 to up to 480 Mbps on USB 2.0, or
40 times faster than with the older technology.

Dual Interface SSD is the only available Flash drive that allows users to
easily remove a single SSD from one system and use it in a 2nd system with
different interface requirements. This makes it an optimal solution for
applications that require that the SSD have a high-speed
SATA interface for
digital mission data storage in a combat system and an industry standard
USB interface for direct
connection to a debriefing station or other PC.
STEC is demonstrating
the new Zeus drive this week at the
Defence Systems & Equipment International
2005 Exhibition and Conference in London.
Since Zeus Dual Interface SSDs offer both SATA and USB connectivity,
customers can work with an SSD design that is extremely flexible and optimized
for use as a removable
mass memory storage device. The product removes complexity from the design of
host applications by eliminating the need to design interface adapters for the
