Product Benefits

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 reflected as of March 2013.

Dual processor
Twice the processing power to 

maximize performance.

™

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 significant 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 fine tune the 

head positioning to a higher degree 

of accuracy. 

™

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-specific, time-limited error 
recovery (TLER)
Prevents drive fallout caused by the 

extended hard drive error-recovery 

processes common to desktop 

drives.

™

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.

Thermal extended burn-in test
Each drive is put through extended 

burn-in testing with thermal cycling to 

ensure reliable operation.

Dynamic fly height technology
Each read-write head’s fly 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.
