MODE 0~4 reflects the HDD data transfer rate. The higher the
MODE value is, the better is the HDD data transfer rate. But it
does not mean that you can select the highest MODE value just
as you like, you first have to be sure that your HDD supports
this MODE, otherwise the hard disk will not be able to operate
normally.
