Three-Year Limited Warranty As an industry-leading hard drive manufacturer, Western Digital stands behind their surveillance storage solutions with a 3-year limited warranty 6 included with every WD Purple drive. 1. 1MB = 1 million bytes, 1GB = 1 billion bytes, and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment. 2. 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. 3. 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. 4. 1TB through 3TB (WD30PURZ) support up to eight bays; 3TB (WD33PURZ) and 4TB and above support up to 16 bays. 5. 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. 6.
