All specifications above are based on native configurations.
**
One GB equals one billion bytes and 1TB equals one trillion bytes when referring to hard drive capacity.
Accessible capacity may vary depending on operating environment and formatting.
*** During periods of drive idle, some offline activity may occur according to the S.M.A.R.T.
specification, which may increase acoustic and power to operational levels.
†
Seagate does not recommend operating at sustained case temperatures above 60°C.
Operating at higher temperatures will reduce useful life of the product.

Rated workload
Average annualized workload rating: <55 TB/year.
The AFR specification for the product assumes the I/O workload does
not exceed the average annualized workload rate limit of 55 TB/year.
Workloads exceeding the annualized rate may degrade the product
AFR and impact reliability as experienced by the particular
application. The average annualized workload rate limit is in units of
TB per calendar year.
