Summary
As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar Green drives make it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation. WD has reduced power consumption by up to 40 percent compared to competitors' drives with the combination of WD's IntelliSeek, IntelliPark, and IntelliPower technologies. 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. 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*. 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 yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.

Description
Ideal for PCs, external storage, and other devices that require lower power consumption and cool, quiet operation.

Features
Reduced power consumption: By adjusting the rotational speed, using bigger data buffers, parking the drive's head, and optimizing how the drive seeks and caches data we have reduced the power consumption by up to 38 percent
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
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
