WD Purple 4TB Surveillance 3.5″ Internal Hard Drive
WD Purple 4TB Surveillance 3.5″ Internal Hard Drive, AllFrame Technology, SATA 6 Gbit/s, 180TB/yr, 128MB Cache
WD Purple drives are designed to meet the challenges of 24×7 video surveillance recording. These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. 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. With WD Purple drives, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive WD AllFrame technology helps reduce frame loss and improve overall video playback.
Industry-Leading Storage. Surveillance You Can Trust Western Digital has provided surveillance-grade storage for more than a decade. With WD Purple surveillance storage, drives are engineered for high temperature, always-on surveillance systems so you can rely on quality video when you need it most.
Western Digital's Exclusive WD AllFrame Technology All WD Purple drives are equipped with AllFrame technology, which helps reduce video frame drops and improves video recording and playback.
Enhanced Workload Ratings WD Purple drives feature a workload rating of up to 180TB/year – up to three times that of desktop drives – to handle the unique demands of mainstream video surveillance DVR and NVR systems.
Multiple Cameras, Multiple Streams Modern recorders now support multiple video streams per camera. WD Purple drives support up to 64 single-stream HD cameras. With so many options, you have the flexibility to upgrade or expand your security applications in the future.
Designed for Reliable Operation Engineered for reliability with an MTBF of up to 1 million hours, WD Purple drives feature tarnish-resistant components and support for storage systems with up to 16 drive bays. WD Purple hard drives are designed with RAID error recovery control to help reduce failures in supported video recorders.
