Disclosures

1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.
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.
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.
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.
