Product information: Purple Surveillance 4TB 64 MB Cache 3.5" SATA-III HDD (40PURX)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.
