Western Digital Caviar Green WD10EACS, Caviar Green WD5000AACS, Caviar Green WD7500AACS Specifications

• IntelliPower™– A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, WD Caviar Green drives consume less current during startup allowing lower peak loads on systems as they are booted.

• IntelliSeek™– Calculates optimum seek speeds to lower power consumption, noise, and vibration.

• IntelliPark™– Delivers lower power consumption by automatically unloading the heads during idle to reduce aerodynamic drag.

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 Green drives yield an 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 CO

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*. By using environmentally-conscious PCs with our WD Caviar Green drives on board, large organizations with many desktop computers can minimize their carbon footprint and save real money on electricity costs.

GreenPower Technology

Environmental sustainability is important to us at Western Digital. One of the best ways we can make a positive impact on the environment is to help our customers – PC and external drive manufacturers – offer products that consume less electricity. To that end, WD has designed an eco-friendly hard drives with GreenPower technology for WD desktop, enterprise, CE and external hard drive products.

Based on extensive customer input toward supporting ENERGY STAR 4.0 compliance and incorporating the latest in engineering technology, we developed this platform to bring more energy efficient hard drive options to our customers.

Consuming less power lowers the electricity bill. By how much? It depends on several factors: The system type (desktop computer, server, external hard drive, or DVR); how many hours per year the drives run; other factors such as air conditioning costs; and the cost of a kilowatt hour.

Here’s a chart that takes into account these factors and estimates the savings that can be achieved in each segment:
