Momentus 5400.3 PATA Blade Server Product Manual, Rev. B
*One Gbyte 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.
***Typical notebooks will pull power to the drive when entering S3 and S4; while in the S3 and S4 states, drive sleep and drive standby
modes will not contribute to battery power consumption.
