Seagate to demo solid-state drive with 12Gbps SAS

Little-known fact: Seagate sells solid-state drives. The SSDs are targeted strictly at enterprise customers, but they exist. Seagate now says it's whipped up a version of its Pulsar.2 SSD with 12Gbps SAS connectivity, and it's going to demonstrate the drive at the SCSI Trade Association Technology Showcase tomorrow.

The company doesn't quote specs or performance details, but it claims the drive can operate at a full 12 gigabits per second and is backward-compatible with "all previous generations of SAS speeds." SAS, of course, is short for Serial Attached SCSI; you're probably not gonna see it on consumer drives, but it's commonplace in the server and workstation realms. Assuming 8b/10b encoding, a sustained 12Gbps transfer speed would work out to about 1.2GB/s, twice the speed of 6Gbps SAS and SATA.

Seagate adds that the 12Gbps SAS standard is "currently stable and expected to be finalized by the end of the year." The first wave of 12Gbps SAS products will start to become available next year, though Seagate doesn't expect "general availability" until the second half of 2013.
