With 1.2 million hours MTBF @ 100% duty cycle, 5-year warranties, up to 3.0 Gb/s SATA technology, and best-in-class vibration tolerance, Western Digital RAID Edition SATA drives offer the best combination of superior reliability, high capacity, and optimum performance for enterprise applications.
 
  • 1.2 million hours MTBF at 100% duty cycle
  • NCQ and RAFF
  • Serial ATA 300 MB/sec Interface (Serial ATA II 3Gb/sec)
  • 16 MB cache buffer size
  • 7200 rpm
  • 5-year warranty
Superior reliability - Designed and manufactured to server-class standards to provide best-in-class enterprise reliability in high duty cycle environments, these drives have the highest available reliability rating on for high-capacity drives.

Fast - With a next-generation Serial ATA interface, up to 3.0 Gb/s data transfer rate, native command queuing (NCQ), and 16 MB cache, these drives deliver optimum performance.

Low power - Active Power Save delivers best-in-class seek mode power consumption through an advanced WD firmware which conserves power in active seek modes without degrading performance.
