Storage media maker Seagate is said to be working on a 3TB Constellation ES disk drive that is expected to arrive in stores later this year, according to unnamed sources speaking to TheRegister. The enterprise-class drive would have a 6GBps SAS interface and have the largest capacity from any of its kind in 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 rumored 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 and can be found in systems from Apple, Dell, HP and others.
