Annualized Failure Rate (AFR)*
0.73% based on 8760 POH
Maximum Rated Workload*
Maximum rate of <300TB/year
Workloads exceeding the annualized rate may degrade the drive MTBF and impact product reliability. The Annualized Workload Rate is in units of TB per year, or TB per 8760 power on hours.
Workload Rate = TB transferred * (8760 / recorded power on hours).

Notes
* One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.
* See Section 2.10, "Reliability" for rated MTBF device operating condition requirements
