It boils down to fragmentation. If you use most (80-100%) of your disk
then when you run the disk at capacity it won't be able to allocate
objects anywhere near as optimally as it can when the disk is at least
half empty. The biggest thing that'll hit your performance is fragmentation.

That said, 20% is a bit silly. I'd go with ~50-70%. Anything more and
you definitely are asking for trouble.
