SanDisk has introduced a 32-gigabyte, 2.5-inch Serial ATA (SATA) interface model, broadening its solid state drive (SSD) product line for the portable computer market. Coming just two months after SanDisk introduced a 1.8-inch SSD for ultra-portable laptops, 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 laptop 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."

The vast majority of laptop 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 laptop manufacturers can switch to the SanDisk SSD without altering their hardware designs.

SanDisk SSDs deliver 2 million hours mean time between failures (MTBF), approximately six times more than laptop hard disks. In laptop 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.

SanDisk 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 watts. Since SSDs don’t need a motor, bearings or a moving head mechanism, they generate much less heat than hard disk drives.

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