During periods of drive idle, some offline activity may occur according to the
SMART specification, which may increase acoustic and power to operational levels.

| Maximum Rated Workload |
Maximum rate of <550TB/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). |
