  INDUSTRY’S HIGHEST CAPACITY NEARLINE DRIVE.

  WD RE SAS hard drives are available in capacities ranging from 1 TB to 4 TB to suit even the most demanding storage needs.
  

  HIGHEST PERFORMANCE FOR BUSINESS-CRITICAL APPLICATIONS.

  WD RE delivers 6 Gb/s transfer rates, sustained sequential data rates of up to 182 MB/s and high random I/O rates.
  

  DESIGNED FOR QUALITY AND RELIABILITY.

  With a 1.4 million hour MTBF, this high performance drive delivers the highest level of reliability for 24×7 operation in up to 100% duty cycle applications.

  DUAL PORT, FULL DUPLEX CONNECTIVITY.

  Offers higher reliability, performance and data availability by eliminating single points of failure, designed for leading business-critical Enterprise topologies.

  ENVIRONMENTALLY CONSCIOUS.

  In addition to being RoHS compliant, WD RE is built with halogen-reduced components.
  

  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.

  DUAL STAGE ACTUATOR TECHNOLOGY.

  A head positioning system with two actuators that improves positional accuracy over the data track(s). 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.

  RAFF.

  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.

  RAID-SPECIFIC, TIME-LIMITED ERROR RECOVERY (TLER).

  Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
  

  ULTRA COMPATIBLE.

  An ultra-fast 6 Gb/s SAS interface enables easy integration into SAS storage subsystems while delivering twice the interface speed of traditional 3 Gb/s SAS nearline hard drives.
