WD Gold™

Datacenter Hard Drives

Scale it in gold.

With up to ten times the workload capacity of desktop drives, WD Gold™

hard drives employ advanced technology to deliver among the best in

reliability, capacity, power eciency and performance. Designed for a

multitude of Datacenter-specic applications, WD Gold™ hard drives are

perfect for high-availability server and storage arrays that demand the most

robust storage device available with 24/7 premium customer support.

Product Benets

Full range of nearline capacities

From entry-level servers to high

end enterprise storage systems, WD

Gold™ hard drives oer the capacities

required for the most demanding

datacenter environments.

High workload capability

Delivering both performance

and reliability to any datacenter

environment, WD Gold™ hard drives

are designed to handle workloads up

to 550TB per year which is among the

highest workload capability of any 3.5-

inch hard drive.

High level of reliability

With up to 2.5 million hours MTBF,

WD Gold™ hard drives deliver one

of the highest levels of reliability

and durability for yearly operation

(24x7x365) within the most demanding

storage environments.

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 signicant performance

improvement in high vibration

environments over our desktop hard

drives.

RAID-specic, time-limited error

recovery (TLER)

Reduces drive fallout caused by the

extended hard drive error-recovery

processes common to desktop drives.

Dynamic y height technology

Each read-write head’s y height is

adjusted in real time for optimum

reliability.

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.

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.

Premium support

Dedicated 24x7 over the phone

support is included with every WD

Gold™ hard drive.

Applications

Enterprise servers, datacenter environments, enterprise storage systems, data warehousing/mining, enterprise NAS, and high end surveillance systems.

The WD Advantage

WD puts datacenter products through extensive Functional Integrity Testing (F.I.T.) prior to any product launch. This testing ensures our products consistently meet

the high quality and reliability standards of the WD brand. Following a FIT test the Enterprise System Group (ESG) testing validates interoperability with HBAs,

operating systems, and drivers, to ensure an even greater level of quality, reliability, and peace of mind.

WD also has a detailed Knowledge Base with helpful articles and software utilities. Our customer support lines have long operational hours to ensure you get the

help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details.

2 As 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.

3 WD 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.

4 Controlled unload at ambient condition.

Product MTBF and AFR specications are based upon a 40°C base casting temperature and typical system workload of 219TB/year. Workload is dened as the amount of user data transferred to or from the hard drive. Product is designed for workloads up to 550TB/year.
