Product Description

Western Digital's WD RE 7200 RPM hard drives are engineered to thrive in a high duty cycle RAID system while still offering traditional low cost-per-capacity desktop value. Designed and manufactured to enterprise-class standards, WD RE drives provide RAID-specific time limited error recovery (TLER) to prevent drive fallout caused by extended drive error-recovery processes and are tested to 1 million hours MTBF. These EIDE and SATA drives include an 8 MB cache for faster time to data and Fluid Dynamic Bearings to reduce heat, vibration, and noise.

Main Features:

  • Time-limited error recovery (TLER) - improves compatibility with RAID adaptors; 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,
  • 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
