WD Gold Hard Drive 4TB SATA 6Gb/s Product Description
Massive capacities suit even the extremely demanding datacenter,enterprise server,or cloud storage needs.
Designed for high-intensity applications
Designed to handle high workloads delivering both performance and reliability to any datacenter environment.
The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
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 desktop 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.
Multi-axis shock sensor
Automatically detects the subtlest shock events and compensates to protect the data.
RAID-specific,time-limited error recovery (TLER)
Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Designed for quality and reliability
These drives ensure one of the highest level reliability ratings for high-capacity enterprise storage needs.
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.
