Quote from the review at HardwareZone:
“Western Digital’s latest Media Center external drive combines the best of their desktop storage solution with features supporting all the various solid-state media devices. Built specifically for both the corporate or home user who needs a portable backup device in addition to doubling its support for various card standards, the Western Digital Media Center aims to please with both performance, compatibility and flexibility.
Housed in a sturdy plastic case with a metallic look and feel, the Media Center is equipped with Western Digital’s latest 250GB 7,200RPM hard disk drive. From the model number displayed when the Media Center is plugged into the test system, it’s actually based on the drive with the Ultra ATA-100 interface (WD2500JB). “
