Today Seagate updated its Barracuda line with an industry first. The 2TB Barracuda XT drive uses a 6Gbps SATA interface and has twice as much theoretical bandwidth as existing SATA II drives. It gives the disk up to 600MBps in burst transfers. When it comes to actual speed, the drive is still pretty fast with a 140MBps sustained transfer rate and Seagate’s 64MB of onboard cache.

The Barracuda XT will support SATA II and 1.5Gbps SATA systems and should still reach its sustained speed on those models.

Seagate expects to ship the drive later this week for $299.
