Cool, quiet, eco-friendly. WD Caviar Green drives use less power and support quieter, cooler-running desktop PCs and external storage devices.

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.

• 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 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 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.
• 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.
