*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.

Rated workload

Average rate of <55TB/year. The AFR specification for the drive assumes the I/O workload

does not exceed the average annualized workload rate limit of 55TB/year. Workloads
exceeding the annualized rate may degrade the drive AFR and impact product reliability.
The average annualized workload rate limit is in units of TB per year, or TB per 8760
power-on hours. Workload rate limit = TB transferred × (8760/recorded power-on hours).
