SanDisk on January 4 introduced a 32GB 1.8-inch solid state drive (SSD) as a drop-in replacement for the standard mechanical hard disk drive. The product will initially be aimed at enterprise users and is now available for OEMs.

According to Eli Harari, SanDisk CEO, the inclusion of the SanDisk 32GB SSD in a notebook PC could increase the end-user price by around $600 in the first half of 2007, he added.

The announced SanDisk SSD achieves a sustained read rate of 62MB per 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.

The company said 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 (HDD).

The SanDisk SSD also only consumes 0.4 watt during active operation versus 1.0 watt for an HDD, the company added. SanDisk's 32GB SDD is available for notebook OEMs.
