Product features

  • High-capacity
    WD RE SAS hard drives are available for capacity-intensive storage applications.
  • Peak performance
    Ultra-fast SAS interface maximizes transfer rates while dual-stage actuator technology enables fine-tuned read/write accuracy.
  • Enterprise-class reliability
    Engineered for 24x7 operation with 1.2 million hours MTBF, these drives have the highest available reliability ratings on a high-capacity drive.
  • Compatibility
    An ultra-fast SAS interface enables easy integration into SAS storage subsystems while delivering twice the interface speed of traditional SAS nearline hard drives.
  • Vibration protection
    Enhanced Rotary Acceleration Feed Forward (RAFF) technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time resulting in improved performance and efficiency in densely packed multi-drive systems.
  • NoTouch ramp load technology
    The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
  • Enhanced error correction
    Full internal data integrity protection means the drive finds and corrects potential errors before they ever surface.
  • Environmentally conscious
    In addition to being ROHS compliant, these drives also incorporate a halogen free design.
