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.

Inspiring performance and capacity
WD Blue SSHD introduces high performance 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, SSD like 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.

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.

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.

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.


This drive is compatible with any server that accepts 2.5"x9mm laptop SATA Drives.
