Features
Cache – WD Caviar Blue is available in 2MB, 8MB, and 16MB cache sizes. Bigger cache memory yields faster performance.

Capacity – We offer drives ranging from 40GB to 750GB. Pick the biggest capacity your budget will allow. You can never have too much storage space.

Reliability – We understand the importance of your data, and we are committed to protecting that data with exceptionally reliable products, advanced data protection technology and superior customer support.

Cool – Keeping the drive cool enhances reliability. WD continues to develop new and innovative ways to keep drives cool while they are operating.

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.

Compatible – We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab and Mobile Compatibility Lab to give our customers confidence that our drives will work in their systems.
