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 — By using environmentally-conscious PCs with our WD Caviar Green drives on board, large organizations with many desktop computers can minimize their carbon footprint and save real money on electricity costs.
Cool and quiet — GreenPower™ technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.
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. Additionally, WD Caviar Green drives consume less current during startup allowing lower peak loads on systems as they are booted.
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.
Native Command Queuing (NCQ) — Server feature for performance in random I/O transaction environments. It aggregates many small random data transfers and allows the disk to reorder the commands in a sequential order for faster access.
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.
