Key Features

Fast

* 8 MB cache – Keeps more of your data in high-speed memory for unsurpassed performance in its class. Fast 7200 RPM spindle speed and EIDE (Ultra ATA/100) for burst transfer rates up to 100 MB/s. For even higher performance, consider WD Caviar SE16 SATA 300 MB/s hard drives.

Cool

* Cool operation results in the highest reliability, even in intensely hot environments such as digital video recorders. That’s why these, the coolest on the market, are the drives of choice for the world’s leading consumer electronics and PC manufacturers.

Quiet

* The technology that Tom’s Hardware Guide called “very fast and nearly silent” is used throughout this family of drives. Our WhisperDrive� technology minimizes noise to levels near the threshold of human hearing. To cut seek noise, SoftSeek� technology streamlines read/write seeking algorithms, resulting in more efficient operation.

Ideal For

* High-performance family and business computing. These drives easily handle photo editing and data-intensive multimedia applications. For even higher performance, consider WD Caviar SE16 SATA hard drives.
