Superior storage. Superior surveillance.

WD Purple drives are built for 24/7, always-on, high-definition security systems. With support for up to 8 hard drives and 32 cameras, WD Purple drives are optimized for surveillance. 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 happen when the wrong drive is used in your 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.


Expand your view to 32

WD Purple drives are optimized to support up to 32 HD cameras. With so many options, you have the flexibility to upgrade or expand your security system in the future.


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.

Trust your view with AllFrame™

Missed frames and lost footage is a serious problem when video surveillance needs to be retrieved. With an ordinary desktop hard drive, errors and video interruptions are common, but not with WD Purple. All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to reduce frame loss, improve overall video playback, and increase the number of drives supported within a DVR.


  • Engineered specifically for surveillance security systems.
  • Reduced video frame loss.
  • Tuned for write-intensive, low bit-rate, high stream-count applications typical to most surveillance applications.
  • Prioritized write-operations for maximized surveillance performance.
  • TLER & ATA streaming support.
  • Support for up to eight drives.

Less power. More efficient.

Low power consumption is a necessity in a high-temperature, always-on surveillance environment. With our exclusive IntelliSeek technology, WD Purple drives are able to calculate optimum seek speeds, keeping power consumption low so ambient noise and vibrations that would damage an ordinary desktop drive are at a minimum.

Three year warranty

As an industry-leading hard drive manufacturer for over 20 years, WD stands behind their surveillance storage solutions. With a 3-year limited warranty included with every WD Purple drive, you can build a reliable DVR you can trust.


Disk Utilities and Migration Tools

Acronis True Image WD Edition can clone drives, backup your operating system, applications, settings and all of your data, while also having the ability to securely wipe any data you no longer need. You can quickly and easily deploy a new hard drive to your PC or laptop and automatically migrate your operating system, applications, and all of your important data, including images, music, and documents.
