SAS SSD - serial attached SCSI solid state drive

From Yenra

On January 8, 2008, Toshiba announced the expansion of its line up of NAND-flash-based solid state drives (SSD) into the enterprise storage market with the company's first Single Level Cell (SLC) NAND-based SSDs. The drives feature the serial attached SCSI (SAS) interface, which is expected to gain momentum in the high-performance enterprise storage market in 2009. Toshiba's new enterprise SSDs address market demands for the performance advantages and power savings of solid state storage for applications in servers, direct-attached storage and network-attached storage.

Toshiba's initial enterprise SSD lineup utilizes the company's latest high endurance SLC NAND and will offer random Input/Output operations Per Second (IOPS) up to 25,000/20,000 for a 4Kbyte data block size read/write, and storage capacities of up to 100 gigabyte (GB). The drives will be available in 2.5-inch small form factor and offer many enterprise features, such as dual ported SAS redundancy and non-volatile cache. Samples of the new drives will be available in late first quarter of 2009, with mass production in the second quarter.
