7.4 S.M.A.R.T. Save Attribute Values
This command causes the device to immediately save any updated attribute values to the device’s non -volatile
memory regardless of the state of the attribute autosave timer. Upon receipt of this command from the host,
the device sets BSY, writes any updated attribute values to non-volatile memory, clears BSY, and asserts INTRQ.
This command is effectively a no-operation command.
