Combine the capacity of a traditional hard drive with the performance of an SSD using the 4TB Blue 3.5" Solid State Hybrid Drive from WD . Designed for both Windows and Mac workstation and gaming environments, this SSHD features a 4TB capacity and 8GB of MLC NAND flash memory.

Utilising an advanced set of algorithms, this WD Blue SSHD tracks data usage, prioritising frequently-used data for fast access in the solid state portion of the device, and adapting, learning, and optimising as new applications and command requests change over time. These algorithms reside in the SSHD firmware, enabling it to make determinations of which data to store in the NAND flash memory without any influence from the host or related storage device drivers. This can help to increase overall system performance, resulting in quicker system boots, faster application loads, and improved responsiveness when compared to traditional hard drives.

In addition to its 4TB capacity and 8GB of MLC NAND flash memory, this SSHD is also built with a 3.5" form factor, a SATA III 6 Gb/s interface, a 64MB cache, a 150 MB/s max host to/from drive (sustained) data transfer rate, 300,000 load/unload cycles, < 1 in 10 14 non-recoverable read errors per bits read, Advanced Format (AF), and RoHS compliance.

Key Features

Performance and Capacity

  • WD Blue SSHD introduces NAND flash SSD technology to the storage capabilities of traditional hard drive storage, uniting both to help enhance the computing experience. A single WD Blue SSHD drive provides an optimised, all-in-one solution which helps to synergise SSD-like performance and hard drive 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 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 SSD-like speed

Self-Learning Technology

  • Utilising an advanced set of algorithms, WD Blue SSHDs track data usage, prioritising frequently-used data for fast access in the solid state portion of the device, adapting, learning, and optimising 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

Synergy Delivers Value

  • This WD Blue SSHD is equipped with 8GB of NAND flash to deliver fast, SSD-like performance over high-capacity storage, lowering the price per 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 instals 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

8GB NAND Flash

  • 8GB 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

Gaming, Owned

  • A gaming rig equipped with a WD Blue SSHD can deliver faster game loads, auto saves, and help reduce lag between levels when compared to traditional hard drives. Fast drive response also helps result 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
