The typical enterprise HDD is a 2.5-inch unit. The drives in the enterprise market are smaller than what we typically see in the consumer desktop environment so more HDDs can be fit in the same space. The more drives that can be squeezed into a storage device the less space the enterprise needs for computing needs. Seagate has announced the first 2.5" 1TB HDD for enterprise markets.

The new HDD is in the Constellation.2 line and is aimed specifically at storage applications in servers. The HDD uses the 6Gb/s interface and promises best in class power consumption. Seagate says that the new HDD is appropriate for use in direct attached storage, network attached storage, and storage area network environments.

"Data center managers continue to seek out more efficient storage technologies without sacrificing performance, while still meeting capacity growth requirements," said John Rydning, research director for IDC. "Reaching the 1TB capacity in a small form factor design gives IT managers more options to meet capacity requirements with efficient storage platforms. IDC expects the use of capacity-optimized drives like Seagate's 1TB Constellation.2™ to increase by more than 50% from 2010 to 2014."

The new 1TB drive fits into the line along with the existing 250GB and 500GB HDDs. The new HDD and the others in the line can be had with the 6Gb/s SATA or 6Gb/s SAS interfaces. Dell will ship systems using the new HDD late this month according to Seagate.
