The right drive for the right job. 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 24/7 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. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback. WD Purple 8TB* and higher drives have additional performance headroom to support a new generation of AI-enabled NVRs, video analytics appliances, and deep-learning servers. * As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.
