The WD WD44PURZ Purple 4TB SATA Hard Drive is designed to meet the challenges of 24x7 video surveillance recording. This drive is 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 the WD Purple WD44PURZ drive, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive WD AllFrame technology helps reduce frame loss and improve overall video playback.
