Yeah, you need ext4 to get TRIM support, but I believe I read that it
is very important to ONLY add "discard" if your drive supports it. I
think I read that bad things could happen otherwise (no idea what sort
of bad things). Being that my drive is a 1st gen Intel and they never
ended up adding TRIM with a firmware update like they said they would,
it was easy for me...just leave it out.

The noatime is one optimization that I suppose I did make, but not
intentionally. It's always been my habit to add that option on any
drive I've ever setup
