Desktop Green Power
Based on WD’s exclusive GreenPower™ technology, these drives are designed to deliver power savings as the primary attribute. As hard drive capacities increase, the power required to run those drives increases as well.
1 TB hard drives currently available have a typical power consumption rating greater than 13.5 watts. WD Caviar GP drives yield average drive power savings of 4-5 watts over competitors’ drives making it possible for our energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.
In desktop computers this power savings equates to reducing CO2 emission by up to 13.8 kilograms per drive per year — the equivalent of taking a car off the road for 3 days each year*.
Green PC
Savings can be achieved with high capacity external storage devices using GreenPower drives. External USB, FireWire and Ethernet drives can save up to $14 per year in electricity costs depending on the power-on-hours and power supply efficiency.
There are a lot of computer systems, network servers, and external storage devices out there consuming a lot of electricity, if we can make a difference by helping to reduce the power consumption of just a small percentage of them, we believe we will have made a positive impact on the environment.
