SanDisk introduced a 32-gigabyte
(GB)a, 1.8-inch solid state drive (SSD) as a drop-in replacement for the
standard mechanical hard disk drive. Initially aimed at enterprise [more] users
as the first step toward mass consumer adoption, SanDisk SSD offers
field-proven durability to keep mobile PCs working in the toughest of
conditions and improves the overall user experience.
Previously, large capacity
flash-based drives had been used primarily by the military, aerospace and
telecom industries, which demanded high performance and reliability under
challenging environmental conditions. But now the declining cost of NAND flash
memory has made SSD a viable and economically attractive alternative to
existing technologies in a wider variety of applications, including mobile PCs
aimed at enterprise and consumer users.
Using NAND flash enhanced by
SanDisk’s patented TrueFFS flash management technology, SanDisk SSD delivers
two million hours mean time between failures (MTBF). With no moving parts, it
does not need to spin into action or seek files in the way that conventional
hard disk drives do. These characteristics, combined with SanDisk's advanced
flash management technology, make it possible for SanDisk SSD to deliver excellent
performance compared with hard disk drives and competing solid state drives.
The SanDisk SSD announced today
achieves a sustained read rate of 62 megabytes (MB) per second and a random
read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transferiii
– more than 100 times faster than most hard disk drives. Taking advantage of
this performance, a laptop PC equipped with SanDisk SSD can boot Microsoft
Windows Vista Enterprise
in as little as 35 seconds. It also can achieve an average file access rate of
0.12 milliseconds, compared with 55 seconds and 19 milliseconds, respectively,
for a laptop PC with a hard disk drive.
Another advantage of SanDisk SSD
is its extremely low power consumption rate compared to the hard disk drive: 0.4
watt during active operation versus 1.0 watt. This is particularly important to
extend the battery life for the benefit of enterprise road warriors. These
results enable new operating systems, such as Microsoft Vista, to provide
mobile PC users with a superior overall system experience.
SanDisk SSD 1.8-inch 32GB solid
state drive is now available for original equipment manufacturers. It is the
first in a range of solutions that SanDisk will be offering to bring flash to
the mainstream mobile PC market.
