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.
