Ratings & Reviews

Disclosures

  1. One terabyte (TB) = one trillion bytes. Actual user capacity may be less due to 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 X (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
  3. Projected values. 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, typical workload and 40°C device-reported temperature. Derating of MTBF and AFR will occur above these parameters, up to 550TB/year and 60°C (device-reported temperature). MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
