SanDisk Launches 32GB Solid State Drive To Replace Notebook HDDs
SanDisk Corporation introduced a 32GB, 1.8-inch solid state drive (SSD) as a drop-in replacement for the standard mechanical hard disk drive. Initially aimed at enterprise users as the first step toward mass consumer adoption, SanDisk SSD offers 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 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.
The new SanDisk SSD achieves a sustained read rate of 62 megabytes/second and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transfer – more than 100 times faster than most hard disk drives. According to the press release, 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.
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.
