Seagate launched its first 2TB enterprise-class disk drive as part of a new family of near-line SAS and SATA drives.

The new Constellation 2.5-in. and Constellation ES 3.5-in. drives come in Serial Attached SCSI 6Gbit/sec. or Serial ATA 3Gbit/sec. models and include a feature that allows them to shut down when not in use to save power.

The Constellation ES stores up to 500GB on four platters with an areal density of 368 gigabits per square inch.

Western Digital Corp. released a 2TB drive last month, but it was a SATA drive aimed at desktop and external storage applications
