Kanguru may have beaten them to the punch, but we suspect Western Digital will attract a fair bit more attention with its own move into greener hard drives, with the company today announcing its new GreenPower initiative. According to the company, the new family of drives will encompass desktop, enterprise, CE and external hard
drives, and will include drives ranging in size from 320GB to 1TB. Those will apparently each boast up to a 40% savings in power consumption, which could translate to a $10 savings per drive each year on your power bill. A GreenPower version of Western Digital's 1TB Caviar GP hard drive will be the first out the gate, shipping first in the form of a WD My Book external drive later this month, with a standard desktop version set to follow in August. Other GreenPower drives will then apparently start shipping in volume within the third quarter of this year.
