The award-winning WD Caviar family provides the best combination of performance, reliability and value for today's entry-level and mainstream desktop systems. Western Digital's WD Caviar hard drives allow host computers to send and receive data at higher rates resulting in increased performance and data integrity. Giant magnetoresistive heads meet the increasing capacity requirements and achieve significant increases in areal densities and performance levels. This Western Digital exclusive feature, automatically detects, isolates and repairs problem areas on the hard drive to prevent the loss of data. This proactive data-reliability feature improves drive performance through a continuous self-tuning process that performs scans and repairs while the drive is idle. Data Lifeguard is both an enhancement and an extension to Western Digital's S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) system that monitors and predicts the performance of hard drives.
