SanDisk announced their 32-gigabyte (GB), 1.8-inch solid state drive (SSD) as a drop-in replacement for the standard mechanical hard disk drive. The SSD is targeting hard disk drive replacements in notebook computers. The declining cost of NAND flash memory has made SSD a viable and economically attractive alternative for users seeking high performance and durability, including mobile PCs aimed at enterprise and consumer users.
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 to hard disk drives and competing solid state drives.
The SanDisk SSD 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 transfer, which is more than 100 times faster than most hard disk drives. With this performance, a laptop PC equipped with SanDisk SSD can boot Microsoft Windows Vista in as little as 35 seconds.
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 users concerned about battery life. These results enable new operating systems such as Microsoft Vista to provide mobile PC users with an overall superior system experience.
“Once we begin shipping the 32GB SSD for notebook PCs, we expect to see its increasing adoption in the coming years as we continue to reduce the cost of flash memory," said Eli Harari, SanDisk CEO. It is projected that the inclusion of the SanDisk 32GB SSD in notebook PCs could increase the end-user price by around $600 in the first half of 2007, he added.
SanDisk’s 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.
