Western Digital has announced a new environmentally friendly GreenPower family of WD desktop, enterprise, CE and external hard drive products.

The new GreenPower family will come in capacities from 320 gigabytes to one terabyte, and will save up to 40% in hard drive power consumption, or, if cold-hard cash is what floats your boat, as much as $10 per drive per year.

The new products will meet the "ENERGY STAR 4.0" compliance criteria.

The first drive that will feature WD’s new GreenPower technology is the WD Caviar GP 1TB.

The WD Caviar GP 1TB hard drive will first ship in July in the My Book range of storage appliances, with 1TB desktop shipments following in August.

GreenPower versions of WD RE enterprise drives and WD AV consumer electronics drives will ship in volume within Q3.
