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).
