Product Benefits

High workload rating

Delivering dependable performance to any storage environment, WD Gold™ hard drives are designed with a workload rating up to 550TB per year1, among the highest of any

3.5-inch hard drive.

Enterprise-class storage to rely on

With up to 2.5 million hours MTBF,

WD Gold hard drives deliver reliability and durability, are built for yearly operation (24x7x365) within the most demanding storage environments, and are backed with a 5 year limited warranty.

HelioSeal™ Technology

Featured in over 15 million Western

Digital hard drives shipped2, HelioSeal™ technology allows for higher capacities and less

turbulence on large storage arrays.

And now on its 4th generation design, HelioSeal™ technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust.

Vibration protection

Enhanced RAFF™ technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus WD’s desktop drives in highvibration environments.

RAID-specific, time-limited error recovery (TLER)

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

Dynamic fly height technology

Each read-write head’s fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.

Dual-stage actuator technology

WD Gold drives feature a dualstage actuator head positioning system for a high degree of accuracy. The primary stage provides course displacement while the secondary stage uses piezoelectric motion to fine tune the head positioning to a higher degree of precision.

Compatibility testing

All WD Gold hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters to ensure ease

of integration for a plug and play solution.

7200RPM-Class

This 7200RPM-class hard drive delivers the fastest performance with the highest workload rating of any HDD in WD’s lineup. Ensure you have the most capable hard drive regardless of the application with

WD Gold.
