It is the same (since it is an argument to the kernel).

48x is the the maximum value for data-discs. This value can only be 
reached seldom and if, then usually only in the outer 0.5 centimeters of 
a disc.

Audio extraction is different from reading data, so this value is 
smaller in most cases.

I prefer quality and my drive also does only 4x to 8x but that's okay 
for me.

Kind regards,
