WD_BLACK drives provide optimal performance for storing large multimedia files such as photos, videos, and application files. They are performance-optimized and perfect for gaming. WD_BLACK drives offer enormous capacity for storing your growing game library. The WD_BLACK drive is equipped with a dual-core processor, which provides double the computing power compared to a single-core processor to maximize drive performance. With 256 MB of cache in the 4 TB - 10 TB models, WD's Dynamic Cache technology enhances real-time performance by allocating and optimizing the cache between read and write operations. It reduces system-induced vibrations and optimizes performance and reliability. The software "Acronis True Image WD Edition," available as a free download, can clone drives and back up your operating system, applications, settings, and data.
