WD Re™ Datacenter Capacity HDD

Durable capacity storage for high-availability deployments
WD Re datacenter hard drives offer up to 4 TB capacities and are available with SAS or SATA interface. With the highest error tolerance and MTBF of any capacity-optimized drive, WD Re delivers the durability and 24x7x365 reliability required in tightly packed vibration prone multi-drive systems. 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.

Product Benefits

Industry’s highest capacity nearline drive
Massive capacities up to 4 TB suit even the most demanding datacenter or cloud storage needs.

Designed for heavy application workloads
Designed to handle up to 550 TB per year in any heavy application datacenter with the highest workload capabilities of any WD 3.5 hard drive. Up to 6 Gb/s transfer rates and sustained sequential data rates of up to 182 MB/s, deliver performance and reliability to any datacenter environment.

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 in the most demanding storage environments.

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 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.

Environmentally responsible
In addition to being RoHS compliant, these drives are built with halogen reduced components.

Self Encrypting Drive (SED) option
Optional secure model for encrypting drives – Utilizing an AES 256 bit encryption engine for Crypto erase capability, WD supports both industry standard commands of the Sanitize Feature Set and also the Security Feature Set which utilizes the Secure Erase Unit (SEU) enhanced mode bit.

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.

Dual processor
Twice the processing power to maximize performance.
