One "odd" condition I ran into twice with the ssd + btrfs were
filesystems about half full but cant write to because the filesystem was
full!

After messy crashes it seemed like btrfs would "lose" some
files/sectors/whatever and the only way I could recover was an erase
cycle (IBM 520 series).  It wasnt sub-volumes or other wrinkles as far
as I could see, just that btrfs/trim and the underlying disk didn't
agree and I couldn't figure out why ...

For "my" use case, having good backups (regularly tested by actually
needing to use them :) have been an integral part of my ssd
"experiences" :)  On the other side, the apple laptop with ssd + btrfs
on root has been problem free.
