Western Digital WD Caviar RE 160Gb, 7200RPM 160GB EIDE/ATA internal hard drive

WD Caviar RE 160Gb, 7200RPM Life in a desktop computer doesn't compare to the extreme environment in an always-on, high duty cycle RAID system. What's needed is a drive engineered to thrive in a high-intensity RAID system while still offering traditional low cost-per-capacity desktop value. That drive is the WD Caviar RE. Designed and manufactured to enterprise-class standards, WD Caviar RE drives provide enhanced reliability in a 24x7, continuous duty cycle environment.

Time-limited error recovery (TLER) – improves compatibility with RAID adapters; prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop hard drives.

1 million hours MTBF – meets enterprise-class reliability standards.
8 MB cache – provides a higher percentage of cache hits and significantly faster time to data than industry-standard 2 MB versions.

Fluid Dynamic Bearings (FDB) – improve hard drive reliability; reduce heat, vibration and noise.

Data Lifeguard Tools ™ – software utility that works in conjunction with the embedded Data Lifeguard™ features (including shock protection, an environmental protection system, and embedded error detection and repair features) to make hard drive installation, management, and diagnostics simple and worry-free.
