WD Caviar Blue SATA II hard drives combine 300 MB/s transfer rate and 8 MB cache for industry leading performance. Yes, these reliable drives are lightning fast, but they still deliver technologically advanced acoustics and cool operation.

Fast - The one-two performance punch of 300 MB/s transfer rate, state-of-the-art performance for SATA drives, and 8 MB cache make the WD Caviar Blue family the fastest desktop-class hard drives available.

Cool - Cool operation means the highest reliability even in high-heat environments such as personal video recorders. That's why these drives, the coolest on the market, are the drive of choice for the world's leading consumer electronics manufacturers as well as the world's leading PC makers.

Quiet - The technology that Tom's Hardware called "very fast and nearly silent" is repeated in this family of drives. Western Digital has minimized noise to levels virtually below the threshold of human hearing with WhisperDrive technology. And to cut seek noise, SoftSeek technology streamlines read/write seeking algorithms, resulting in the drive operating more efficiently when accessing and writing data.
