One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on operating environment and formatting.

* See 

Section 2.11, "Reliability"

 for rated MTBF device operating condition requirements.

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).
