Rated workload Average rate of <55TB/year. The MTBF specification for the drive assumes the I/O workload
does not exceed the average annualized workload rate limit of 55TB/year. Workloads
exceeding the annualized rate may degrade the drive MTBF and impact product reliability.
The average annualized workload rate limit is in units of TB per year, or TB per 8760 power-
on hours. Workload rate limit = TB transferred × (8760/recorded power-on hours).
