Depends on the definition of "storage device", I guess. If it's physical media, then OS X doesn't. If it's the controller, then OS X does. But since the intent is to have the data reach persistent storage, it has to be the physical media.

My guess is that since people know all of this, they'll just keep working around it as they already do. Newbies to OS X development will get bitten unless they know what to look for.
