Ultra-fast SAS storage
WD S25 delivers 6 Gb/s transfer rates, sustained sequential data rates up to 155 MB/s, and fast average read seek times of 3.8 ms or less.

Industry’s highest reliability rating
With a field-tested MTBF of up to 1.75 million hours, these high performance drives are perfect for enterprise server and enterprise storage applications. (BKHG models)

Low power consumption
This 2.5-inch SAS drive requires less than 8 watts to operate.

Ultra-cool operation
The small form-factor, 70 percent smaller than 3.5-inch drives, allows more system airflow resulting in lower cooling costs.

Rotary Acceleration Feed Forward (RAFF)
Optimizes operation and performance when the drives are used in vibrationprone, multi-drive chassis.

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.

Environmentally conscious
In addition to being ROHS compliant, these drives also incorporate a halogen free design.


This drive is compatible with any server that accepts small form factor (SFF) SAS hard drives
