Do watch out for that sector alignment gotcha on Linux.. New tools tend to get it right, old ones won't.
That is the case as far as partition alignment at 4k blocks (parted /dev/sda check-align optimal 1), but Ty Ts'o had a blog post indicating it was non-trivial to also align the mdadm and lvm layers. That was for the much larger SSD write-erase blocks, but IIRC it would apply equally to 4k blocks. Can't find the article now, though... :-/
