High performance, high capacity, high reliability, and cutting-edge technology make up WD Black, the ideal drive for those who demand only the best. Industry-leading warranty WD Black carries the highest available warranty protection on the market, a 5-year limited warranty. High performance electronics. Dual processor - Twice the processing power to maximize performance. Dynamic Cache - WD's dynamic caching algorithm improves performance in real time by optimizing cache allocation between reads and writes.
