WD Purple drives are designed to meet the challenges of 24/7 surveillance recording. These drives are specifically designed for video surveillance to withstand the high temperature fluctuations and vibrations in the equipment found in an NVR environment. The average desktop drive is designed to operate only in short bursts and not in the harsh, continuous 24/7 operation environment of a high-definition video surveillance system. With WD Purple drives, you get reliable, surveillance-specific storage that is compatible with a wide variety of security systems. Exclusive AllFrame™ technology helps reduce dropped frames and improve overall video playback.
