Great buy for the money. I moved my current 100GB hard drive to this as my primary drive and partitioned the rest of it for music and pictures. Works great...

Product Overview

The original.
These drives are built utilizing the tried and true proven technology of the original award-winning WD Caviar 3.5-inch hard drives for desktop computers.

SATA or PATA interface
While SATA has become the industry standard interface, WD continues to manufacture desktop drives with a PATA interface for unique or legacy systems.

Built to the highest standards of quality and reliability, these drives offer features and capacity at an affordable price.

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

SATA - Serial ATA (SATA) hard drives are quickly becoming the new standard. Motherboard manufacturers now include SATA inputs on their boards. Because of their considerably narrower cables, SATA hard drives provide increased airflow and less clutter and in the computer system compared to PATA drives.

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