Industry's highest capacity near line drive Massive capacities suit even the most demanding datacenter or cloud storage needs.
Designed for heavy application workloads Designed to handle heavy application datacenter with the highest workload capabilities of any WD 3.5 hard drive. Up to 6 Gbp transfer rates and sustained sequential data rates of up to 182 Mbps, 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 24 x 7 x 365 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. 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.
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.
Dynamic fly height technology Each read-write head's fly height is adjusted in real time for optimum reliability.
