As hard drive capacities increase, the power required to run those drives increases as well. WD 1TB Lower Power 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.

24x7 reliability - These drives are designed to last in high temperature always-on, power PC, workstation, streaming digital audio/video environments such as PVR/DVR, IPTV, and video surveillance systems.

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 - GreenPower?technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.

Massive capacity - Capacities up to 1 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 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. View demo >

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.

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