Superior storage. Superior surveillance.
WD Purple™ drives are built for 24/7, always-on, high-definition security systems. With support for up to 8 bays and 32 cameras, WD Purple™ drives are optimized for surveillance systems. WD Purple™ surveillance storage also comes with WD’s exclusive AllFrame™ technology, so you can confidently create a security system tailored to the needs of your business. Using AllFrame™ technology, WD Purple™ drives improve ATA streaming to reduce errors, pixilation, and video interruptions that could happen in a video recorder system.
The right drive for the right job.
WD Purple™ drives have been engineered specifically for surveillance, so they’re able to withstand the extreme heat fluctuations and equipment vibrations within an DVR environment. 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.
Wide compatibility. Seamless integration.
WD Purple™ hard drives are built with compatibility in mind, so you can quickly and seamlessly add capacity to your surveillance system. With a wide range of industry-leading enclosures and chipsets supported, you’re sure to find the DVR configuration that’s right for you.*
