^footnote1 1MB < 1 million bytes, 1GB < 1 billion bytes, and 1TB < 1 trillion bytes. Actual user capacity may be less depending on operating environment.

^footnote2 Projected values for model number WD221KRYZ and WD202KRYZ. 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 220TB/year and device temperature 40°C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year and 60°C device temp. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.

^footnote3 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.
