WD Se™
Datacenter Capacity HDD
Optimal Storage for NAS and Scale-Out Architectures
WD’s Se hard drives provide an ideal solution for
scale-out datacenters, delivering a cost-effective combination
of performance, reliability, and workload capability while
maintaining the hardiness of a true enterprise-class design. All
WD datacenter storage devices are designed from the ground
up to deliver optimal performance and maximum data integrity
while running 24x7x365 in demanding multi-slot environments.

Applications
Ideal for bulk cloud storage, replicated environments, content delivery networks (CDNs), SMB to high-end network attached storage (NAS), backup and archiving.
Product Benets
Cost effective enterprise-class
storage
Get the right blend of performance,
reliability and capacity and keep your
total cost of ownership low.
24x7x365 reliability
Choose the storage foundation
specically designed for SMB to
high-end NAS and large-scale
datacenter replication environments
running 24x7x365.
Maximum capacity for hyperscale
environments
Build a massive data footprint with
capacities up to 4 TB - 144 TB per
square foot.
Dual processor
Twice the processing power to
maximize performance.
Dynamic y height technology
Each read-write head’s y 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 signicant
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 ne tune the
head positioning to a higher degree
of accuracy.
Environmentally responsible
In addition to being RoHS compliant,
these drives are built with halogen
reduced components.
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-specic, time-limited error
recovery (TLER)
Prevents drive fallout caused by the
extended hard drive error-recovery
processes common to desktop
drives.
NoTouch™ramp load technology
The recording head never touches
the disk media ensuring signicantly
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
efcient media format that enables
increased areal densities.
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 longer 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.

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 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.
2WD hard drive products manufactured and sold worldwide after June 8, 2011, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU.
3Controlled unload at ambient condition.
4 Product MTBF and AFR specications are based upon a 40°C base casting and system workloads of up to 180 TB/year (workload is dened as the amount of user data transferred to or from the hard drive).
