SDDs Gain SAS and SATA

Arthur Cole

Another first in the solid-state drive (SSD) market was reported by STEC Inc. with the expansion of the company's FibreChannel-based Zeus-IOPS device to include 3 Gbps SAS and SATA interfaces.

 

The drive is a standard 3.5-inch form factor with built-in NAND Flash media. The company bills it as a rapid-access solution that allows enterprise users to avoid having to increase the capacity of battery-backed RAM or aggregate numerous hard disks to improve I/O performance. Read access is rated at 20 microseconds (yes, micro, not milli), while write access comes in at 60 microseconds.

 

Other specs include 52,000 sustained random read IOPS, 17,000 sustained random write IOPS, 250 MBps sustained sequential reads and 200 MBps sustained sequential writes.

 

SATA versions are expected by the end of the year, while the SAS drives are due in early '08.
