WD Blue
PC SSHD
The best of both worlds –
HDD capacity meets SSD-like speed.
WD Blue Solid State Hybrid Drives (SSHD) combine
a generous amount of NAND flash SSD technology
and massive HDD storage capacity into a single drive.
WD engineers team up the best of SSD and HDD to
produce a hybrid that can increase overall system
performance – resulting in quicker system boots,
faster application loads, and improved responsiveness
when compared to traditional hard drives.

Product Features
Inspiring performance
and capacity
WD Blue SSHD introduces highperformance NAND flash SSD
technology to the huge storage
capabilities of traditional HDD
storage - uniting both to enhance
the computing experience. A single
WD Blue SSHD drive provides an
optimized, all-in-one solution which
synergizes SSD-like performance,
and massive HDD storage capacity
in a single device.
Work faster, smarter,
and more efficiently
Power users such as digital artists,
photographers, and gamers will
welcome WD Blue SSHD’s ultrafast read and write speeds when
it comes to their large creative
and multimedia files. The capacity
limitations of a standalone SSD are
no longer an issue; WD Blue SSHD
has the capacity for an entire digital
portfolio, with outstanding, SSDlike speed at a manageable price.

Self-learning technology
Utilizing an advanced set of algorithms,
WD Blue SSHDs track data usage,
prioritizing frequently used data for
fast access in the solid state portion
of the device, adapting, learning and
optimizing as new applications and
command requests change over time.
These advanced algorithms reside in
the SSHD firmware, enabling it to make
intelligent determinations of which data
to store in NAND flash memory, without
any influence from the host or related
storage device drivers. By pairing
SSD-like performance with massive
hard drive capacity, WD has created an
intelligent hybrid drive that truly offers
the best of both worlds.
Synergy delivers value
WD Blue SSHD is equipped with the
optimal amount of NAND flash to
deliver fast, SSD-like performance over
high-capacity storage, significantly
lowering the $/GB compared to the
higher cost and lower capacity of
standalone SSDs.
CAPACITIES

4 TB
Simple installation with
no special software required
The WD Blue SSHD hybrid drive
is self-contained in a traditional
HDD form factor, and installs
as easily as any traditional hard
drive without special drivers or
downloads required. WD Blue
SSHDs are compatible with most
typical computer configurations,
including PC and Mac.
8 GB NAND flash delivers
blazing performance
An optimal amount of built-in NAND
flash SSD technology enables
WD Blue SSHDs to perform at up
to four to five times faster than
traditional 5400 rpm HDDs, based
on PCMark Vantage*.
* As measured by PCMark Vantage
storage benchmarking software.
INTERFACE

Gaming, owned
A gaming rig equipped with WD
Blue SSHD can deliver faster game
loads, auto saves, and can reduce
lag between levels, when compared
to traditional hard drives. Ultra-fast
drive response results in a smoother
gaming experience and the added
capacity means gamers can store
more of today’s larger game files.
Applications
WD Blue SSHDs are performance-tested for use in PC and Mac OS, high-performance workstations and gaming systems.*
* WD hard drives are designed and tested for use in specific applications and environments. This ensures that your hard drive is compatible with and functions
properly in your application. Our hard drives are warranted against defects in materials and workmanship in the system for which they were designed. Use
in systems other than for what the hard drive was designed could result in compatibility problems that affect proper function, unrelated to material and/or
workmanship defects. For best results, be sure to select the appropriate product for your application by consulting our product spec sheets on our website at
www.wd.com or by calling our customer support line where we would be happy to help you through the selection process.

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.
