Disclosures

  1. 1MB = 1 million bytes, 1GB = 1 billion bytes, 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment.​
  2. Projected Values. When final, MTBF are 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 will occur above these parameters, up to 550TB writes per year. MTBF do not predict an individual drive’s reliability and do 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 × (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.​
