Product Features

Solid performance
With SATA and PATA interfaces, and cache sizes up to 32 MB, this series of drives offers a full range of performance features.

Capacity

WD Caviar Blue drives are available in capacities from 80 GB to 1 TB because you can never have too much storage space.

IntelliSeek

Calculates optimum seek speeds to lower power consumption, noise and vibration.

ShockGuard

Instantaneously protects the hard drive against damage from bumps and vibrations while it is running. This technology enables WD Caviar drives to achieve industry-leading shock specifications.

Ultra-cool and quiet

Keeping the drive cool enhances reliability. WD continues to develop new and innovative ways to keep drives cool while they are operating which helps protect the drive and the data stored on it.
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.

1 As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification sheet. Visit www.sata-io.org for details. 2 WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The RoHS Directive 2002/95/EC of the European Parliament, which is effective in the EU beginning July 1, 2006, aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances. 3 Maximum burst rate running the Mode 5 Ultra ATA transfer mode. 4 Controlled unload at ambient condition. 5 The term of the limited warranty may vary by region.
