Western Digital 4TB Purple Surveillance HDD
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.
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.
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.
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.
