• The WD Purple Pro HDD, with OptiNAND technology in 22TB(1), delivers big capacity in a drive engineered for advanced, AI-enabled, always-on smart video recorders, appliances, and servers. | (1) 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.
• Western Digital's exclusive AllFrame AI technology improves ATA streaming to help reduce frame loss and improve overall video playback.
• WD Purple Pro drives are optimized to handle up to 64 single-stream HD cameras(2) as well as many of the latest smart cameras that transmit multiple streams. | (2) Single stream per camera @ 3.2Mbps (1080p, H.265, 25 fps). Results may vary depending on camera resolution, file format, frames per second, software, system settings, video quality, and other factors.
• With a workload rating up to 550TB/year(3), these drives are built to keep up with heavy video data capture and analysis. | (3) 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.
• The reliable WD Purple Pro is engineered with an MTBF of up to 2.5 million hours(4) for advanced smart video solutions that operate in 24/7 environments. | (4) Projected values. When final, MTBF, and AFR specifications will be based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions, workload of 220TB/year, and drive temperature of 40°C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year, and 65°C drive temperature. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
