Western Digital Corp. has announced new hard drives that use up to 40% less power than competing drives. The serial ATA drives are part of a new GreenPower-branded line (RE2-GP), with 500GB, 750GB and 1TB capacities. They use on average 4 to 5 watts less than similar-size drives from Hitachi GST, Fujitsu, Seagate and other major suppliers.
Western Digital said four branded technologies boost the power efficiency of the new drives
