Make the RAM drive bigger if you can, you won't need more than 8GB anywhere. Stick an entire game or program in there with symbolic links for compatibility, and it'll load crazy fast.
I put Waterfox in it. It loads 10x faster. So I think I'm going to put 8GB in it since I already paid for the program. I was wondering if I should delete the cache files after I fill it up? Or should I just keep it maxed out and not put anymore cache files in it.
