Solid State Drive launched to replace hard disks in mainstream notebook computers
The 2.5-inch SSD is now available to PC manufacturers as a drop-in replacement for hard disk drives.
"The SanDisk 2.5-inch SSD brings the extreme durability, outstanding performance and low power consumption of solid-state flash memory to the entire notebook computer market," said Amos Marom, vice president and general manager of the Computing Systems division at SanDisk.
"As SanDisk continues to drive innovation in flash memory, the per-gigabyte price of SSD storage will come down and SSD capacity will go up. PC manufacturers and consumers will find it easier and easier to move away from rotating hard disks to the superior experience of SSDs," said Marom.
The vast majority of notebook computers manufactured today use 2.5-inch hard disk drives. The 2.5-inch SSD fits in the same internal slot as 2.5-inch hard disks, so notebook manufacturers can switch to the SSD without altering their hardware designs.
The key benefits of SSDs for computer manufacturers and their customers are:
* Reliability. SSDs deliver 2 million hours mean time between failures (MTBF), approximately six times more than notebook hard disks. With no moving parts, SSDs are also much less likely to fail when a notebook computer is dropped or exposed to extreme temperatures.
* Performance. In notebook computers, data moves to and from an SSD more than 100 times faster than data moving to and from a hard disk. SSDs offer a sustained read rate of 67 megabytes (MB) per second3 and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transfer.
* Power efficiency. SSDs have minimal power requirements, with savings rated at over 50 percent compared with a hard disk drive — 0.9 watts during active operation versus 1.9 watts7.
* Cool and quiet. Because SSDs don’t need a motor, bearings or a moving head mechanism, they generate much less heat than hard disk drives. SanDisk SSDs are also completely silent, while hard disk drives always make at least some noise during read and write operations.
The 32GB, 2.5-inch SanDisk SSD is available now to computer manufacturers, with initial pricing of $350 for large volume orders.
