It takes more than a supercharged processor to keep your PC at the head of the pack. It takes a new class of hard drive as well. The WD Expert 7200 RPM family from Western Digital leaves conventional 5400 RPM drives far behind with 33% faster disk transfer rates. You also get the enhanced performance and data integrity of the new Ultra ATA/66 interface, as well as Data Lifeguard, WD's exclusive automatic defect detection, isolation and repair technology.
