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). |
