I'm creating a partition so I can have the windows 10 install on-demand when I need it, not sure why I didn't think of this before. The question of the allocation unit size popped up in my head when I was getting ready to create the partition. Since the number and size of files on it will always the same, if I take the size on disk (4,285,284,352 bytes), divide that by the number of files (944), would that be the optimal allocation unit size? (4,539,496 bytes, but the max option is 2M)
