Western Digital today announced a 320GB HDD for enterprises that runs at 7,200RPM. The drive is available with a Serial ATA or EIDE interface. WD Caviar RE drives feature Time Limited Error Recovery (TLER), which helps prevent drive fallout caused by standard extended desktop hard drive error-recovery processes.
Prior to WD's development of TLER, hard drive
fallout when using desktop drives in RAID (Redundant Array of Independent
Disks) applications was a common experience among systems integrators and
storage manufacturers. By addressing the differences between single-user and
multi-user workloads, WD Caviar RE drives implement RAID-specific TLER, which
improves drive compatibility with RAID controllers resulting in markedly
improved system reliability.
WD Caviar RE drives also feature one million hours MTBF (Mean Time Between
Failure), offering systems builders and storage system manufacturers high
reliability in high-duty cycle applications, where continuous performance is
WD Caviar RE hard drives are currently shipping in volume and are

WD3200SD) is $229 USD and WD Caviar RE 320 GB with EIDE interface (model no.
