Western Digital 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. WD Blue SSHDs are performance tested for use in PC and Mac OS, high-performance laptops, All-in-One PC's and gaming systems.

  • 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 ultra-fast 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 Fast 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 5400RPM HDDs, based on PCMark Vantage.
  • 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.
