Not really; there has unfortunately been very little (or no)
optimization of ext4 for SSDs at this point ...

It'd probably be an allocator heuristic change but nobody's looked into
that yet.

Once we get ext4 raid-geometry-aware, we can probably use some of that
geometry info to better match up with the erase block sizes on an SSD at
least...
