*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 b

attery power consumption.
