SanDisk Launches 32GB 2.5-Inch Solid State Drive

SanDisk Corporation today broadened its solid state drive (SSD) product line for the portable computer market with the introduction of a 32-gigabyte 2.5-inch Serial ATA 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.

The key benefits of SanDisk SSDs for computer manufacturers and their customers are:

  • Reliability. SanDisk SSDs deliver 2 million hours MTBF, approximately six times more than notebook hard disks. With no moving parts, SanDisk 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. SanDisk SSDs offer a sustained read rate of 67 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 and access files at an average speed of 0.11 milliseconds. A notebook using a hard disk requires an average 48 seconds to boot and an average 17 milliseconds to access files.
  • Power efficiency. 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. This is particularly important in extending battery life for road warriors, enabling them to remain productive while in transit.
  • Cool and quiet. Because SanDisk SSDs donít 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. SanDisk SSDs will be demonstrated at the CeBIT show in Hannover, Germany, from March 15 to 21, 2007, in Hall 23, Stand B28, and will be featured on March 16 during the PressExpoUSA @ CeBIT 2007 event.
