Disclosure

1: One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes). Actual user capacity may be less due to operating environment.
2: Advanced Format drive: 4K (4096-byte) physical sectors.
3: Portion of buffer capacity used for drive firmware.
4: Based on internal testing; performance may vary depending on host environment, drive capacity, logical block address (LBA), and other factors. 1MiB = 1,048,576 bytes (2²⁰), 1MB = 1,000,000 bytes (10⁶).
5: 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 temperature 40C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year and 60°C ambient (65°C device temp). MTBF and AFR ratings do not predict an individual drive's reliability and do not constitute a warranty.
6: Idle specification is based on use of Idle_A.
7: 5°C ambient temperature, 60°C device reported temperature.
