*One GB equals one billion 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.
