Product Benefits
Cost effective enterprise-class
storage
Get the right blend of performance,
reliability and capacity and optimize
your total cost of ownership.
24x7x365 reliability
Choose the storage foundation
specifically designed for large-scale
datacenter replication environments
running 24x7x365.
High capacity for hyperscale
environments
Build a massive data footprint with
capacities up to 6 TB - 216 TB per
square foot.
Designed for quality and reliability
Datacenter drives undergo at
least 5 million hours of functional
testing, and over 20 million hours of
comprehensive interoperability testing
in an extensive array of server and
storage systems. Please see the
product AVL list on our website for
more information.
FORM FACTOR
3.5-inch
Dynamic fly height technology
Each read-write head’s fly height is
adjusted in real time for optimum
reliability.
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 desktop
drives.
Dual actuator technology (2 TB
and above)
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.
ROTATIONAL SPEED
7200 RPM
StableTrac
The motor shaft is secured at both
ends to reduce system-induced
vibration and stabilize platters for
accurate tracking during read and
write operations. (2 TB and above)
Multi-axis shock sensor
Automatically detects the subtlest
shock events and compensates to
protect the data.
RAID-specific, time-limited error
recovery (TLER)
Reduces drive fallout caused by the
extended hard drive error-recovery
processes common to desktop
drives.
™
CAPACITIES
1 TB to 6 TB
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.
Thermal extended burn-in test
Each drive is put through extended
burn-in testing with thermal cycling to
ensure reliable operation.
Advanced Format (AF)
Technology adopted by WD and
other drive manufacturers as one of
multiple ways to continue growing
hard drive capacities. AF is a more
efficient media format that enables
increased areal densities.
Applications
Ideal for bulk cloud storage, distributed file systems, replicated environments, cost-efficient RAID architectures, and content delivery networks (CDNs).
The WD Advantage
WD puts our datacenter products through extensive Functional Integrity Testing (F.I.T.) prior to any product launch. This testing ensures our products consistently
meet the high quality and reliability standards of the WD brand. Following a FIT test the Enterprise System Group (ESG) testing validates interoperability with HBAs,
operating systems and drivers to ensure an even greater level of quality, reliability and peace of mind.
WD also has a detailed Knowledge Base with helpful articles and software utilities. Our customer support lines have long operational hours to ensure you get the
help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details.

As 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 SATA 6 Gb/s transfer rate calculated according to the Serial ATA specication published by the SATA-IO organization as of the date of this specication sheet. Visit
www.sata-io.org for details.
