I understood these drives were now becoming much more common, especially enterprise-grade drives. I know there were problems switching from 512/512 drives to 512/4096, but as you say I thought they were pretty much addressed. I think it must be a couple of years ago now though, that I heard (on LWN) enterprise drives were apparently switching over to 4096/4096. With NO 512 emulation fall-back.
