SanDisk launches 2.5-Inch Solid State Drive for notebook computers
SanDisk Corporation has extended its solid state drive (SSD) product line for the portable computer market with the introduction of a 32 gigabyte (GB), 2.5-inch Serial ATA (SATA) interface model, compatible with most mainstream notebook designs.

Coming just two months after SanDisk introduced a 1.8-inch SSD for ultraportable notebooks, the 2.5-inch SSD is now available to PC manufacturers as a drop-in replacement for hard disk drives.

The vast majority of notebook computers manufactured today use 2.5-inch hard disk drives. The SanDisk 2.5-inch SSD fits in the same internal slot as 2.5-inch hard disks, so notebook manufacturers can switch to the SanDisk SSD without altering their hardware designs.

This new device delivers 2 million hours mean time between failures (MTBF), approximately six times more than notebook hard disks. With no moving parts, SanDisk SSDs are also less likely to fail when a notebook computer is dropped or exposed to extreme temperatures.

The company says in notebook computers, data moves to and from an SSD more than 100 times faster than data moving to and from a hard disk. SanDisk SSDs offer a sustained read rate of 67 megabytes (MB) per second and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transfer. As a result, notebooks equipped with a 2.5-inch SanDisk SSD can boot Microsoft Windows Vista Enterprise in as little as 30 seconds. Current notebooks using a hard disk require an average 48 seconds to boot and an average 17 milliseconds to access files.

Another advantage is the reduced power requirements. SanDisk SSDs provide savings rated at over 50 percent compared with a hard disk drive. The devices use 0.9 watts during active operation versus 1.9 watts on standard hard drives. This is important in extending battery life on mobile computers.

The 32GB, 2.5-inch SanDisk SSD is available now to computer manufacturers, with initial pricing of US$350 for large volume orders.
