24 hours after we exclusively revealed in Australia, the launch of a complete new portable storage system from Seagate comes news that Seagate is set to launch a 3TB Constellation ES disk drive.

Ideal for organisations serving video content the drives are primarily designed for heavy duty use.

Originally revealed on the Register the enterprise-class drive would have a 6GBps SAS interface and have the largest capacity from any of its kind in the Seagate’s range. The largest current Constellation ES is a 2TB, 7,200RPM unit.

A 1TB version of a 2.5-inch Constellation ES drive is also expected mid-year, and become the highest-capacity 2.5-inch drive. Also rumoured is a new Savvio 2.5-inch drive that would eclipse the current 600GB, 10,000RPM unit, likely upping capacity to 750GB.

SAS, or Serial Attached SCSI drives, are used heavily in servers.
