The right drive for the right job.
WD Purpleâ„¢ drives have been engineered specifically for surveillance, so theyâ€™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 Purpleâ„¢, you get reliable, surveillance-class storage thatâ€™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 Purpleâ„¢ 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 youâ€™re protecting loved ones or monitoring your business, WD Purpleâ„¢ offers performance you can trust.
