WD Purple^™ Surveillance Hard Drive - 4TB

WD Purple drives are designed to meet the challenges of 24x7 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 AllFrame™ technology helps reduce frame loss and improve overall video playback.

^footnote1 See https://support.wdc.com/warranty for regional specific warranty details.

^footnote2 Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.

^footnote3 Single stream at 3.2Mbps (1080p, H.265, 25 fps) for WD22PURZ, WD33PURZ, WD42PURZ, WD43PURZ, WD60PURZ, WD62PURZ, WD63PURZ, WD64PURZ, WD84PURZ and 2.6Mbps (720p, H.265, 25 fps) for WD10PURZ, WD20PURZ, WD30PURZ, WD40PURZ. Results may vary depending on camera resolution, file format, frames per second, software, system settings, video quality, and other factors.

^footnote4 MTBF specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions: workload of 90TB/year and drive temperature of 40°C. Derating of MTBF will occur above these parameters, up to 65°C drive temperature. MTBF does not predict an individual drive’s reliability and does not constitute a warranty.

^footnote5 Tarnish resistant components for capacities 3TB (WD33PURZ), 4TB and higher.

^footnote6 1TB through 3TB (WD30PURZ) support up to eight bays; 3TB (WD33PURZ) and 4TB and above support up to 16 bays.
