Dual-Core Processing

The WD Black drive features a dual-core processor that offers twice the processing capability as a standard single-core processor to maximize drive performance, especially for loading games or large multimedia files.

Increased Reliability

WD Black drives are equipped with StableTrac Technology (2 TB and larger models). This secures the motor shaft inside the hard drive to increase reliability and help reduce impact due to system-induced vibrations from other components. By stabilizing the platters inside, WD Black drives result in more accurate tracking in a particular sector during read and write operations, optimizing performance and reliability.
