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. Seagate plans to ship Constellation ES variants
with 500GB and 1TB capacities in Q3, as well. Like the 2TB flavor, these models
will have 3.5" form factors, 7,200-RPM spindle speeds, and a choice of 300MB/s
Serial ATA or 600MB/s serial-attached SCSI (SAS) interfaces. Seagate is also
cooking up 2.5" Constellation hard drives, which will ship later this quarter
with 160GB and 500GB capacities and SATA or SATA connectivity.
