CAVIAR 250GB SPECIAL ED FDB SATA 7200RPM 8MB CACHE
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.
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.
