The Right Drive for The Right Job WD 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. Industry-Leading Storage. Surveillance You Can Trust WD is a worldwide leader in the hard drive industry. With WD Purple™ surveillance storage, you have a drive engineered for high temperature, always-on surveillance systems so you can rely on quality video playback when you need it most. Whether you’re protecting loved ones or monitoring your business, WD Purple™ offers performance you can trust.
