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.
• 16 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.
  
  SATA-specific Features:
  
• FlexPower - connector technology that accepts power from either industry-standard or new SATA power supplies.
• Hot plug support - allows swapping of hard drives without having to power down the system or reboot; promotes system design flexibility, data availability, and serviceability.
• Backplane compatibility - uses the SATA industry standard connector which includes alignment ears and 3-stage electrical mating sequence, designed specifically for backplanes and hot pluggability.
• SATA latching connector - provides a secure connection between the hard drive and the cable connector via a locking latch mechanism.
  

Recommended: Western Digital's Serial ATA cable with SecureConnect provides a 500 percent stronger cable-to-drive connection than first-generation SATA hard drives and cables; for use with Western Digital SATA drives only.

IMPORTANT: Because of the time-limited error recovery feature, this product is intended for server applications and is not recommended for use in desktop systems.
