The Western Digital 500GB WD Caviar Blue PATA 3.5" Hard Drive features ample storage, quiet operation and low power consumption. With a 500GB storage capacity, PATA interface and transfer speeds up to 100 MB/s, it's ideal for unique / legacy systems that are not compatible with SATA. The Caviar Blue benefits from ShockGuard technology that protects the drive mechanics from shocks. It also uses NoTouch, which prevents the recording heads from resting on the disk during spin up, spin down, and when the drive is off. This results in a more reliable drive due to the limited head wear. The Caviar Blue is also tested rigorously to ensure compatibility with most systems.
PATA Interface
The PATA interface is ideal for many unique and legacy systems that aren't compatible with SATA interfaces
Ample Storage
With a 500GB storage capacity for a 3.5" form factor drive, the WD Caviar Blue offers the highest capacity for space-hungry operating systems with plenty of room left over for photos, music, and video
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
NoTouch Ramp Load Technology
NoTouch keeps the recording heads off the disk surface during spin up, spin down, and when the drive is off. This ensures the recording head never touches the disk surface, resulting in improved long term reliability due to less head wear
Cool & Quiet
Keeping the drive cool enhances reliability. WD continues to develop better ways to keep drives cool while they are operating which helps protect the drive and the data stored on it
