WD Purple 4TB Surveillance Hard Drive

Uncompromising Storage with a WD Purple Surveillance Hard Drive WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 247 always on environment of a high definition surveillance system. With WD Purple, you get reliable, surveillance class storage that's tested for compatibility in a wide range of security systems, and some of our latest models have improved power efficiency. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.
