Unlike Western Digital, Seagate has decided to target the enterprise market with its first 2TB hard drive. The 2TB Seagate Constellation ES won't ship until the third quarter, but it's launching together with several other drives under the same new brand.
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 SAS connectivity.
The firm makes a jab at Western Digital in its press release by saying, "With Constellation ES hard drives, customers don't have to sacrifice performance in order to gain the highest capacities"—likely a reference to the 2TB Caviar Green's slower spindle speed. Seagate isn't necessarily aiming for high power consumption, though. All Constellation drives have a "PowerChoice" feature that purportedly brings "the highest power-reduction savings ever offered in an enterprise-class HDD, and . . . flexible, user-manageable options to deliver power savings without sacrificing performance, data integrity, or reliability."
