Drive Specifications www.seagate.com
*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.
‡
Hybrid time-to-ready specification assumes all needed data files are pinned to flash, Windows 8 environment, and fast BIOS implemented.

Rated workload Average rate of <55TB/year. The MTBF 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 MTBF 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).
