Spins faster than the competition

COMPUTER MANUFACTURER Hitachi has become the first outfit to spin 3TB at 7,200 RPM with its latest Deskstar drive.

ds7k3000The company that ushered in the terabyte hard disk era wasn't able to beat Western Digital to the 3TB punch, however it has managed to best its rival by spinning the five platters in the Deskstar 7K3000 at 7,200 RPM. Aside from the rotational speed, the drive also represents a milestone for Hitachi by becoming the first in its line-up to have a 6Gbps SATA interface.

Hitachi has generally gone with five-platter designs for its high capacity hard drives and given that the platters are spinning at 7,200 RPM, Hitachi quotes an idle power draw of 6.8W, which will increase under load. Aside from power consumption, some will question the need for a 3TB 7,2000 RPM drive that will almost certainly be bought as a file dump, where sequential transfer speeds are more important than random access times.

Until now Western Digital's 3TB hard drive had spun the platters at around 5,400 RPM, though we expect that the firm will announce a 'Black' version of this drive at some point. Nevertheless, Hitachi's 3TB 7,200 RPM monster shows that the consumer hard drive market is still very much a four horse race between Seagate, Western Digital, Samsung and Hitachi.

With Western Digital's 3TB unit going for a tenner shy of £200, expect the Deskstar 7K3000 to be priced at around £200 when it does tip up. µ
