The best of both worlds – HDD capacity meets SSD-like speed. 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.Utilizing an advanced set of algorithms, this WD Blue SSHD tracks data usage, prioritizing frequently-used data for fast access in the solid state portion of the device, and adapting, learning, and optimizing 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.
