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

Annualized Failure Rate (AFR)*
|
0.87% based on 8760 POH
|
Maximum Rated Workload*
|
Maximum rate of <180TB/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).
