Product Benefits

Industry’s highest capacity 
nearline drive
WD Re SATA hard drives are  

available in capacities ranging from 

250 GB to 4 TB to suit even the most 

demanding storage needs. 

Highest performance for 
business-critical applications
WD Re delivers 6 Gb/s transfer rates, 

sustained sequential data rates of 

up to 171 MB/s and high random 

I/O rates.

Designed for quality and reliability
With a field-tested 1.2 million hour 

MTBF, this high performance drive 

delivers the highest level of reliability 

for 24x7 operation in up to 100% 

duty cycle applications.

Dual processor
Twice the processing power to 

maximize performance.

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 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 servers, storage arrays, video surveillance and other demanding applications.
