Massive Capacity WD leads the way with pioneering technology, delivering a massive 3 TB of storage on a single drive. Reduced Power Consumption With reduced power consumption, you can build systems with higher capacities and the perfect balance of performance, reliability, and energy conservation. Cool and Quiet Thanks to WD GreenPower Technology, these drives operate at lower temperatures for increased reliability and low acoustics, making them perfect for ultra-quiet PCs and external drives. Did You Know? It's easy to install an internal hard drive in your computer. The World's Largest Capacity Internal Hard Drive WD Caviar Green SATA drives now offer a massive 3 TB of storage on a single drive, making it the largest capacity internal hard drive in the world. IntelliSeek With IntelliSeek technology, these drives calculate optimum seek speeds to lower power consumption, noise, and vibration. Advanced Format (AF) WD and other drive manufacturers are adopting Advanced Format as one of multiple ways to continue increasing hard drive capacities. This more efficient media format enables increased areal densities. IntelliPower With a fine-tuned balance of spin speed, transfer rate, and caching algorithms, WD Caviar Green drives offer significant power savings and solid performance. They also consume less current during startup, allowing for lower peak loads on systems during boot-up. Ideal for: These drives are perfect for use in PCs, external storage, and other devices that require lower power consumption and cool, quiet operation. They are also tested and recommended for use in consumer-type RAID applications (RAID-0/RAID-1). Perfect for External Drives External drive manufacturers can eliminate the need for a fan in high-capacity products by utilizing the cool and quiet operation of WD Caviar Green hard drives. NoTouch Ramp Load Technology With NoTouch ramp load technology, the recording head never touches the disk media, ensuring significantly less wear to the recording head and media. This also provides better drive protection during transit.
