Durability

WD Re™

Datacenter Capacity HDD

Durable capacity storage for high-availability deployments

WD Re datacenter hard drives offer up to 4 TB capacities and are

available with SAS or SATA interface. With the highest error tolerance

and MTBF of any capacity-optimized drive, WD Re delivers the

durability and 24x7x365 reliability required in tightly packed vibration

prone multi-drive systems. The combination of high-capacity, peak

performance and robust design make WD Re drives ideal for heavy

workload environments, cloud storage, RAID arrays, external storage

arrays, data warehousing and mining applications.

Product Benets

Industry’s highest capacity

nearline drive

Massive capacities up to 4 TB suit

even the most demanding datacenter

or cloud storage needs.

Designed for heavy application

workloads

Designed to handle up to 550 TB

per year in any heavy application

datacenter with the highest workload

capabilities of any WD 3.5 hard drive.

Up to 6 Gb/s transfer rates and

sustained sequential data rates of up

to 182 MB/s, deliver performance

and reliability to any datacenter

environment.

Designed for quality and reliability

With up to 1.4 million hour MTBF,

this high performance drive delivers

durability and the highest level of

reliability for 24x7x365 operation

in 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 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. (2 TB and above)

Environmentally responsible

In addition to being RoHS compliant,

these drives are built with halogen

reduced components.

Self Encrypting Drive (SED) option

Optional secure model for encrypting

drives – Utilizing an AES 256 bit

encryption engine for Crypto erase

capability, WD supports both industry

standard commands of the Sanitize

Feature Set and also the Security

Feature Set which utilizes the Secure

Erase Unit (SEU) enhanced mode

bit.*

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. (2 TB and above)

Multi-axis shock sensor

Automatically detects the subtlest

shock events and compensates to

protect the data.

* SED drives may require TCG-compliant host or controller support. SED

drives may not be available in all countries.

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.

Dual processor

Twice the processing power to

maximize performance.

Applications

High-performance computing, high-reliability cloud storage, RAID arrays, high-availability external storage arrays, data warehousing and mining.

The WD Advantage

WD puts our 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 longer 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.

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
