Hitachi Extends Tbyte Disk Drives

Paul Korzeniowski, July 9, 2008, 5:15 PM

A Gbyte of storage may soon be as outdated as a Mbyte of storage has become. At least, that is the thinking at Hitachi Global Storage Technologies, which today announced its second-generation 1-Tbyte hard drive family, the Deskstar 7K1000 B.

Terabyte disk drives have been popular in the enterprise and are ready to make a move into the consumer market,” notes John Rydning, research director, hard disk drives at IDC.

Hitachi has been successful in the Tbyte part of the enterprise with its five-head Deskstar 7K1000 drives, which were announced in January 2007 and were one of the first to be delivered. Competitors, such as Samsung, Seagate, and Western Digital, focused more on three- and four-platter drives, to differentiate their systems. In response, the second-generation Deskstar 7K1000 B line also comes with three platters.

The hard disk drive family features speeds of 7,200 RPM, and capacities from 160 Gbytes to 1 Tbyte. The drives rely on Hitachi’s perpendicular magnetic recording (PMR) heads and disks, which deliver a maximum of 375 Gbytes of storage per disk. The devices also include some enterprise class functions. The Deskstar 7K1000 B drives, for example, feature a 3-Gbit/s SATA interface and support hot-swap capability, which is needed for high-availability applications.
