WD Xe™
Datacenter Hard Drives
WD Xe SAS hard drives provide up to 900 GB of high
performance storage suitable for both enterprise server and
enterprise storage applications. The ultra-fast 6 Gb/s SAS
interface enables optimum data reliability, availability, and
scalability. In an environment where space and power are
limited, the WD Xe drives are an effective solution for high
performance computing solutions such as power-constrained
data centers, database transaction processing, and rack,
tower, and blade servers.

Product Benets
Ultra-fast SAS storage
WD Xe delivers 6 Gb/s transfer rates,
sustained sequential data rates up to
204 MB/s, and a fast average read
seek time of 3.6 ms.
Industry’s highest reliability rating
2 million hours MTBF.
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 airow resulting in lower
cooling costs.
Dual port, full duplex connectivity
Offers higher reliability, performance
and data availability by eliminating
single points of failure, designed
for high-availability mission-critical
enterprise systems.
Rotary Acceleration Feed
Forward (RAFF™)
Optimizes operation and performance
when the drives are used in vibration-
prone, multi-drive chassis.
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.
Environmentally conscious
In addition to being ROHS compliant,
these drives are built with halogen
reduced components.
5-year limited warranty.
Applications
Performance servers – Database, OLTP, high-performance computing
Performance storage – Data centers and NAS arrays

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 specication published by the INCITS T10 organization as of the date of this specication sheet.
