Editors might not think about it much, but there are a few significant differences between a standard computer hard drive and the hard drives deployed in servers to run around the clock. For instance: reliability. SCSI drives cost more, in part because they're built with better quality components, which means drives suffer less downtime. Western Digital's new enterprise-class 7200RPM WD Caviar RE hard drives help keep costs down, but with improved capacity — now up to 320GB. The new Time Limited Error Recovery feature helps prevent drive fallout caused by a standard desktop drive's error-recovery processes. According to the company, WD Caviar RE drives also feature one million hours MTBF (Mean Time Between Failure).
