I used to developed SSD firmware in the past and our team always used to make sure it would write the data and check the write status. We also used to used to analyze competitor products using bus analyzers and could determine some wouldn't do that. Also in the past many OS filesystems would ignore many errors we returned anyway.

Edit: Here is an old paper on the subject of OS filesystem error handling.
