Product Benefits

High capacity nearline drive

Multiple capacities to suit even

the most demanding datacenter,

enterprise server, or cloud storage

needs.

Designed for high-intensity

applications

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

environment.

StableTrac™

(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

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

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

transit.

Dynamic fly height technology

Each read-write head’s fly height

is adjusted in real time for optimum

reliability.
