Marketing description

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 RE. Designed and manufactured to enterprise-class standards, WD RE drives provide enhanced reliability in a 24x7, continuous duty cycle environment.

Product features

• High performance for business-critical applications
  WD RE delivers 6 Gb/s transfer rates, sustained sequential data rates of up to 171 MB/s and high random I/O rates.
• Designed for quality and reliability
  This high performance drive delivers the high level of reliability for 24 x 7 operation in up to 100% duty cycle applications.
• Vibration protection
  Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives.
• Dual actuator technology
  A head positioning system with two actuators that improves positional accuracy over the data tracks. The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
• StableTrac
  The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
• Multi-axis shock sensor
  Automatically detects the subtlest shock events and compensates to protect the data.
• RAID-specific, time-limited error recovery (TLER)
  Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
• 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.
• Thermal extended burn-in test
  Each drive is put through extended burn in testing with thermal cycling to ensure reliable operation.
• Dynamic fly height technology
  Each read-write head's fly height is adjusted in real time for optimum reliability
