Hitachi introduces "Deskstar P7K500" hard drive series

Power efficiency has become a big selling point among hard drive makers. In July, Western Digital unveiled its 320GB-1TB Caviar GreenPower-series hard drives, which it said reduced power consumption by as much as 40% compared to other models. Today, Hitachi's storage arm—Hitachi Global Storage Technologies—seems determined to one-up Western Digital with the introduction of a new Deskstar P7K500 hard drive series. Hitachi outright claims its new drives are the world's most energy-efficient.

These new Deskstar P7K500 hard drives come in capacities of 250GB, 320GB, 400GB, and 500GB, with one platter per drive for the 250GB model and two platters per drive for the others. All four drives have 7200 RPM spindle speeds, 300MB/s Serial ATA or 133MB/s ATA interfaces, and cache sizes of either 8MB or 16MB. That makes Hitachi's low-power offerings notably different from WD's drives, which use more platters to achieve higher capacities, but spin at slower spindle speeds.
