My storage array abstracts the disks to the point where there is
no need for alignment(if you wanted to try there's no way you could
determine how best to do it), and the intelligent caching on the back
end automatically takes care of doing things like full stripe writes
and maximizing spindle efficiency -

So no I haven't had to do it, and don't plan to in the future.
