STEC s840 SAS SSD

The only non-SATA drive in the lot was the s840 Series SAS SSD serial-attached SCSI drive from STEC. Based in Santa Ana, Calif., the SSD OEM positions its drives as ideal for server and Tier-0 storage arrays and claims throughput as high as 120,000 IOPS. Available in 200-GB, 400-GB and 800-GB capacities, this 6Gb/s dual-port drive uses MLC flash technology to deliver sustained throughput for reads of 500 MB/s and for writes of 300 MB/s. More significant is its transaction rate, which STEC puts at 115,000 IOPS for sequential reads and 104,000 for writes, and maximum random rates of 75,000 for reads and 11,000 for writes. The drive incorporates custom ASICs, proprietary controllers and wear-leveling techniques that allow for 10 full-capacity writes per day for throughout on its five-year warranty period.
