WD RE SAS

Enterprise Hard Drives

WD RE SAS hard drives are engineered to offer data-hungry SAS

storage systems the massive capacity they need without

compromising top-of-the-line performance. Advanced reliability

and data integrity features allow for 24x7 operation in tightly

packed vibration prone multi-drive systems. This

uncompromising combination of high-capacity, peak

performance and best-in-class reliability make WD RE SAS drives

ideal for business critical applications.

Note: Not all products may be

available in all regions of the

world.

High-capacity

WD RE SAS hard drives are available with

up to 2 TB for capacity-intensive storage

applications.

Peak performance

Ultra-fast 6 Gb/s SAS interface

maximizes transfer rates while dual-stage

actuator technology enables fine-tuned

read/write accuracy.

Enterprise-class reliability

Engineered for 24x7 operation with 1.2

million hours MTBF, these drives have the

highest available reliability ratings on a

high-capacity drive.

Compatibility

An ultra-fast 6 Gb/s SAS interface

enables easy integration into SAS storage

subsystems while delivering twice the

interface speed of traditional 3 Gb/s SAS

nearline hard drives.

Vibration protection

Enhanced Rotary Acceleration Feed

Forward (RAFF™) technology includes

sophisticated electronics to monitor the

drive and correct both linear and

rotational vibration in real time resulting in

improved performance and efficiency in

densely packed multi-drive systems.

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.

Enhanced error correction

Full internal IOEDC/IOECC* data integrity

protection means the drive finds and

corrects potential errors before they ever

surface.

Environmentally conscious

In addition to being ROHS compliant,

these drives also incorporate a halogen

free design.

5-year limited warranty

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 SAS 6 Gb/s transfer rate calculated according to the SAS specification published by the INCITS T10

organization as of the date of this specification sheet. Visit www.t10.org for details.

2WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The RoHS Directive 2002/95/EC of the

European Parliament, which is effective in the EU beginning July 1, 2006, aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances.
