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.

Cool and quiet
GreenPower™ technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives. NoTouch™, and IntelliPower™ technologies.
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.

Massive capacity
Capacities up to 2 TB offer the most available capacity for storage-intensive programs and space-hungry operating systems, like Window 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 andcaching algorithms designed to deliver both significant power savingsand 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 ensuringsignificantly less wear to the recording head and media as well asbetter 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 reducesystem-induced vibration and stabilize platters for accurate tracking,during read and write operations.

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.
