Housekeeping advice: A4MK2 banks and sounds


A questions to some of the more pro users of the A4(MK2):
“What is the best (most efficient) way to setup your banks on the +Drive?”

Do i just drop all the sounds on the +Drive and fill up the banks 1 by 1 or is it smarter for instance to divide the banks in themes?
I know that can always use filters to browse through the sounds but i want to be sure that i’m working with the best strategy before is start cleaning up and dividing my banks. Maybe there are other things that have to be kept in mind before choosing how to work with storing sounds.
