Yes, I read that, I was wondering if anyone had actual experience.

Lacking that, I tried to just set it up. So far, it seems like it's 
working, mkfs.ext4 did discards on format, and I can mount with the 
discard option. I'm currently running some batches on it to see if 
speeds keeps up, but it's looking good.
