Datacenter Capacity HDD

Optimal Storage for NAS and Scale-Out Architectures

WD’s Se hard drives provide an ideal solution for scale-

out datacenters, delivering a cost-effective combination of

performance, reliability, and workload capability while maintaining

the hardiness of a true enterprise-class design. All WD

datacenter storage devices are designed from the ground up to

deliver optimal performance and maximum data integrity while

running 24x7x365 in demanding multi-slot environments.

Product Benets

A pedigree in enterprise

WD, one of the storage industry’s

pioneers and long-time leaders,

has a rich history of manufacturing

reliable enterprise storage at an

affordable cost. Built on a

time-tested, multi-generation

platform, with over 28 million

terabytes of enterprise-class

storage shipped*, WD understands

reliable high-quality products are

the backbone of your datacenter

investment.

Designed for quality and reliability

All drives undergo at least 5 million

hours of functional testing, and over

20 million hours of additional testing

under actual workloads in actual

server and storage systems.

*Quantity shipped reected as of March 2013.

Dual processor

Twice the processing power to

maximize performance.

RAFF™rotational vibration

cancellation technology

Enhanced RAFF technology includes

sophisticated electronics to monitor

the drive and correct both linear and

rotational vibration in real time. The

result is a signicant performance

improvement in high vibration

environments over the previous

generation of 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 ne tune the

head positioning to a higher degree

of accuracy.

StableTrac™

The motor shaft is secured at both

ends to reduce system-induced

vibration and stabilize platters for

accurate tracking during read and

write operations.

Multi-axis shock sensor

Automatically detects the subtlest

shock events and compensates to

protect the data.

RAID-specic, time-limited error

recovery (TLER)

Prevents drive fallout caused by the

extended hard drive error-recovery

processes common to desktop

drives.

NoTouch™ramp load technology

The recording head never touches

the disk media ensuring signicantly

less wear to the recording head

and media as well as better drive

protection in transit.

Thermal extended burn-in test

Each drive is put through extended

burn-in testing with thermal cycling to

ensure reliable operation.

Dynamic y height technology

Each read-write head’s y height is

adjusted in real time for optimum

reliability.

Applications

Ideal for bulk cloud storage, replicated environments, content delivery networks (CDNs), large-scale network attached storage (NAS), backup and archiving.

1As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate

or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated according to the Serial ATA specication published by the SATA-IO organization as of the date of this specication sheet. Visit

www.sata-io.org for details.

2WD hard drive products manufactured and sold worldwide after June 8, 2011, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU.

3Controlled unload at ambient condition.

4 Product MTBF and AFR specications are based upon a 40°C base casting and system workloads of up to 180 TB/year (workload is dened as the amount of user data transferred to or from the hard drive).

5 The term of the limited warranty may vary by region. Visit http://support.wd.com/warranty for details.

6 No non-recoverable errors during operating tests or after non-operating tests.
