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.

Annualized Failure Rate (AFR)
<1.0% based on 2400 POH
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.
