WD Purple Surveillance SATA / Serial ATA HDD – Brand New

Western Digital WD40PURX 4TB 3.5in


WD Purple™ Surveillance Hard Drives
Built for 24/7, always-on, high-definition security systems. With a supported workload rate of up to 180 TB/yr1 and support for up to 64 cameras, WD Purple drives are optimized for surveillance systems.

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.
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.

Expand your view to 32
Each WD Purple™ drive is 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.

Improve performance with AllFrame™
WD Purple surveillance-class hard drives are equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increases the number of drive bays supported. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage is a serious problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence you should expect when it’s time to play back and review critical surveillance footage.
