Warranty
* 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 host and S4; while in the S3 and S4 states, drive sleep and drive standby modes will not contribute to battery power consumption.
