Seagate's 2.5-inch enterprise hard drive hits 1TB

From CNET News.com: Though general consumers have had access to 3.5-inch desktop hard drives with up to 3TB of storage or portable external hard drives with 1.5TB, business users have had to live with hard drives with much less space.

That changed today, as Seagate announced its latest in 2.5-inch enterprise hard drives, the 1TB Constellation.2.

According to the hard-drive maker, the drive is the first in its class that offers speeds of up to 6Gbps and 1TB of storage.

Note that 6Gbps hard drives have been available from Seagate before for general consumers, but only in a larger 3.5-inch design. The advantage of the 2.5-inch design is the fact that it can be used in more compact applications as well as applications where the 3.5-inch drives are used.

The Constellation.2 drive comes in 250GB, 500GB, and 1TB capacities with either a SATA or SAS interface. Segate says the drive's advanced second-generation design provides improved data integrity with the new T10 Protection Information standard (PDF) and an increase in reliability (with up to 1.4 million hours MTBF).

The company also says the new hard drive supports Self Encrypting Drive--a technology that keeps important data from unauthorized access in case of loss or theft--and consumes less power than its peers.
