Like other companies hoping to cast a greenish hue on whirring machinery, Western Digital today unveiled GreenPower, a line of internal hard drives that focus on efficiency. That is, they use 40% less power than the competition thanks to some fancy engineering.
The 3.5" SATA drives for desktops, the WD Caviar GP series, are now available, ranging from 320GB to 1TB. The press release claims that switching to a GreenPower 1TB is "the equivalent of taking your car off the road for 14 days each year." The more believable claim is that you will save "up to $10 per drive per year in electricity costs." So it practically pays for itself, in, like, 30 or 40 years.
IntelliPower - A fine-tuned balance of spin speed, transfer rate and cache size designed to deliver both significant power savings and solid performance.
IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise and vibration. View demo >
IntelliPark - Delivers lower power consumption by automatically unloading the heads during idle to reduce aerodynamic drag.
Perpendicular Magnetic Recording (PMR) - Employ PMR technology to achieve even greater areal density.
StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations.

WD'S New GreenPower Hard Drives Reduce Energy Consumption, Helping Protect the Environment[Western Digital]
Company's First One Terabyte Drive Enables Up To 40% Hard Drive Power Savings for Desktop, Enterprise, CE and WD Branded Customers
LAKE FOREST, Calif., July 23 /PRNewswire-FirstCall/—Western Digital Corp. (NYSE: WDC) today announced a new environmentally friendly GreenPower(TM) family of WD(R) desktop, enterprise, CE and external hard drive products. The new GreenPower (GP) family will ship in capacities from 320 gigabytes (GB) to one terabyte (TB), and will save up to 40% in hard drive power consumption, or as much as $10 per drive per year.
Based on extensive customer input toward supporting ENERGY STAR 4.0 compliance and incorporating the latest in engineering technology, WD has delivered the first 3.5-inch hard drive platform designed with power savings as the primary attribute. The GreenPower family gives customers more choices when it comes to purchasing hard drives. The initial drive that will take advantage of WD's new GreenPower technology is the WD Caviar GP. The WD Caviar GP 1TB hard drive will first ship in July in the My Book(TM) range of storage appliances, with 1TB desktop channel shipments following in August.
GreenPower versions of WD RE enterprise drives and WD AV consumer electronics drives will ship in volume within calendar Q3.
ENERGY STAR 4.0 computing systems are designed to enable organizations to minimize their carbon footprint as well as realize significant savings in electricity costs. By WD estimates, in certain applications, the new GreenPower platform can save greater than $10 per drive per year in electricity costs. For example, a data center with 10,000 drives can save $100,000 in annual energy costs, and reduce CO2 emission by 600 metric tons—the equivalent of taking almost 400 cars off the road for a year.
