Western Digital Purple – 4.0TB 3.5″ SATA3 6.0Gbps Surveillance HDD, Intellipower Speed Management, 64MB Cache, 150MB/s Host to/from (Sustained), AllFrame, HD Video Optimised, 2 year warranty

Product Overview
WD Purple 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, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.

Features
Western Digital’s Exclusive AllFrame Technology
All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to help reduce frame loss and improve overall video playback, within a multitude of security video solutions.
Enhanced Workload Ratings
WD Purple drives feature a workload rating of up to 180TB/year2 – up to three times that of desktop drives – to handle the unique demands of mainstream video surveillance DVR and NVR systems.
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 or NVR configuration that’s right for you.
Proactive Storage Management with WDDA
Western Digital Device Analytics (WDDA) provides a wealth of storage device parametric operational and diagnostic data to the system; algorithms interpret the data and direct the system to alert system administrators of specific recommended actions to address potential issues. WDDA is intended to empower OEMs, system integrators, and IT professionals to better monitor and proactively manage supported storage devices to maintain optimal operation.
