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 annual-
ized 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).
