Key Features

Reduced power consumption - WD has reduced power consumption by up to 40 percent compared to standard desktop drives with the combination of WD's IntelliSeek, NoTouch, and IntelliPower technologies.

Helps enable eco-friendly PCs - WD Caviar Green drives yield an average drive power savings of 4-5 watts over standard desktop 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.

Cool and quiet - WD GreenPower Technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.

Massive capacity - Capacities up to 3 TB offer the most available capacity for storage-intensive programs and space-hungry operating systems, like Windows Vista®, with plenty of room left over for photos, music, and video.

Perfect for external drives - External drive manufacturers can eliminate the need for a fan in a high-capacity product with a WD Caviar Green drive, the coolest and quietest in its class.

IntelliPower - A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise, and vibration.

NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. Perpendicular Magnetic Recording (PMR) - Employs 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. (2 TB models only)

Low power spin-up - WD Caviar Green drives consume less current during startup allowing lower peak loads.

Advanced power technology - Electronic components deliver best-in-class low power consumption for reduced power requirements and increased reliability. Ideal For

Environmentally friendly PCs and external storage requiring lower power consumption and cool, quiet operation.
