Designed and manufactured to enterprise-class standards to provide enterprise reliability in high duty cycle environments. With 1.2 million hours MTBF, WD Raptor drives have the highest available reliability rating on a high capacity drive. With a next-generation SATA interface, 1.5 Gb/s data transfer rate, native command queuing (NCQ), and 16 MB cache, these drives deliver optimum performance. RAID-specific, time-limited error recovery (TLER), a feature unique to WD, prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Rotary Acceleration Feed Forward (RAFF) optimizes operation and performance when the drives are used in vibration-prone, multidrive systems such as rack-mounted servers or network storage. WD Raptor features FlexPower connector technology that accepts power from either industry standard or new SATA power supplies.
