WD RE WD1004FBYZ product



Product Benefits
High capacity nearline drive
Multiple capacities to suit even
the most demanding datacenter,
enterprise server, or cloud storage

Designed for high-intensity
Designed to handle workloads up to
550TB per year – among the highest
workload capability of any 3.5-inch hard
drive – delivering both performance
and reliability to any datacenter

(excluding FBYZ models)
The motor shaft is secured at both ends
to reduce system-induced vibration and
stabilize platters for accurate tracking
during read and write operations

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 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

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
With 2.0 million hours MTBF, these
drives ensure one of the highest level
reliability ratings for high-capacity
enterprise storage needs.

Thermal extended burn-in test
Each drive is put through extended
burn-in testing with thermal cycling
to ensure reliable operation.

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

Dynamic fly height technology
Each read-write head’s fly height
is adjusted in real time for optimum
