On a raid volume that will give wrong results and incorrect recovery
behaviour. You need to report correct information. In addition a lot of
software treats repeated errors on flush as a device failure after a
certain count.
If a write to the underlying emulated media fails you know at least which
write fails and usually the page that failed (as you get a short write)
