INSTRUCTIONS

1. MB = one million bytes, 1GB = one billion bytes, and 1TB = one trillion bytes. 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.
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.
3. Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred X (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations
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.
5. This drive is in compliance with the European Union Directive 2011/65/EU and Directive (EU) 2015/863 on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
6. Up to stated speed. 1 MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors.
7. Controlled unload at ambient condition
8. See support.wdc.com/warranty for regional specific warranty details.
