TDK announced this week that it has
developed the smallest in its class solid state NAND flash memory drive.
The drive is roughly the size of a typical notebook hard drive but does not
rely on mechanical rotating platters and read/write heads for operation.
Instead, the tiny drive uses high-speed NAND flash memory and can store up to
32GB of data using sixteen 16 gigabit chips.
According to TDK, the drive is 20% smaller than 2.5.-inch notebook drives. It
also consumes less power and isn't prone to the same failure factors as traditional
drives. TDK's Japanese press release claims:
Along with TDK's "GBDriver RA5" NAND flash memory control LSI,
this semiconductor disc features four super capacitors (optional) for the power
supply interruption assist circuit and a 2.5-inch ATA interface. The GBDriver
RA5 supports "UltraDMA mode2" data transmission mode that boasts a
maximum data rate of 33.3 MB per second.
TDK isn't the only company looking to flash technology. DailyTech
previously reported that Toshiba was also on
the road to releasing its own line of solid state disk drives. The
technology overall has progressed significantly over the past several years,
with prices falling from the thousands of dollars for a 1GB solid state drive
to much more consumer affordable prices. Samsung is also hard
at work on solid state drives as well. No release dates have been set
