Western Digital WD40PURZ Purple 4 TB 5400rpm Surveillance Hard Drive

Western Digital Purple drives have been engineered specifically for surveillance, so they're able to 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.

A disruption to a drive could result in a failure that impacts multiple users, your security archive, or even the entire system. With WD Purple, you get reliable, surveillance-class storage that's tested for compatibility in a wide-range of security systems.
