Disclosures

  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. MTBF specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions (workload of 220TB/year, drive temperature of 40°C). Derating of MTBF will occur above these parameters, up to 550TB/year and 60°C (device-reported temperature). MTBF does not predict an individual drive's reliability and does not constitute a warranty.​
  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. See https://www.westerndigital.com/support/store/warranty-policy for region-specific warranty details.
