WD Re Datacenter Capacity HDD

Durable capacity storage for high-availability deployments.

WD Re datacenter hard drives offer up to 6 TB capacities, SAS or SATA interface, 24x7x365 reliability and the highest error tolerance and MTBF of any capacity optimized drive. The combination of high capacity, peak performance and robust design make WD Re drives ideal for heavy workload environments, cloud storage, RAID arrays, external storage arrays, data warehousing and mining applications.

  • Industry’s Highest Capacity Nearline Drive - Massive capacities up to 6 TB to suit even the most demanding datacenter or cloud storage needs.
  • Designed for Heavy Application Workloads - Designed to handle up to 550TB per year in any heavy application datacenter with the highest workload capabilities of any WD 3.5" hard drive.
  • Designed for Quality and Reliability - With up to 1.4 million hour MTBF, this high performance drive delivers durability and the highest level of reliability for 24x7x365 operation.
  • Dual Processor - With double the processing power, WD RE4 boasts the highest performance of any drive in the RE family.
  • Dual 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. (2 TB only)
  • 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.
  • IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise, and vibration.
  • Dual Port, Full Duplex Connectivity (SaS only) - Eliminates single points of failure, for high-availability mission-critical enterprise systems.
  • Multi-Axis Shock Sensor - Automatically detects the subtlest shock events and compensates to protect the data.
  • Vibration Protection - Enhanced RAFF technology corrects both linear and rotational vibration in real time.
  • 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.
  • RAID Specific, Time Limited Error Recovery (TLER) - Prevents drive fallout caused by the extended hard drive error-recovery.
  • 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.
  • The WD Advantage - WD puts our datacenter products through Functional Integrity Testing (F.I.T.) to ensure high quality and reliability standards. Following a FIT test the Enterprise System Group (ESG) testing validates interoperability with HBAs, operating systems and drivers for additional peace of mind.
  • Self Encrypting Drive (Sed) Option - SAS Drive: Optional secure model for encrypting drives – Utilizing an AES 256 bit encryption engine for Crypto erase capability, WD supports the industry standard implementations of both the SCSI Sanitize command with Crypto Erase and the Trusted Computing Group (TCG) command set. SATA Drive: Optional secure model for encrypting drives – Utilizing an AES 256 bit encryption engine for Crypto erase capability, WD supports both the T13 Sanitize command and the ATA Password support of Secure Erase Unit (SEU).
  • Evironmentally Responsible - In addition to being RoHS compliant, these drives are built with halogen reduced components.
