Quiet Hard Drives - Western Digital Caviar® 1 Terabyte Hard Drive

Western Digital Caviar® GP SATA 1 Terabyte Hard Drive

As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar® GP makes it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.

Key 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, WD has reduced the power consumption by up to 38 percent.
Helps enable eco-friendly PCs
IntelliPower™—A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. For each GreenPower drive model, WD may use a different, invariable RPM.
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.

Ideal For

Environmentally conscious PCs requiring lower power consumption and cool, quiet operation
