There's no contradiction there, just logic that appears to be beyond you. My research has been completed and peer reviewed with agreement across the board. I'm mostly discussing Sandforce controllers because of how you stated they are used in USB flash drives. Still one can't escape that modern USB flash drives are not an equivalent to a modern SSD. Maybe a 3+ year old SSD, but nothing modern. With modern being a Samsung 840 or a Crucial M4 or equivalent. The question wasn't answered by you alone. It was a group effort by myself, jbarley, Fishrrman, marzer, Weaselboy, iStiggy, and yourself.
Lastly, just drop the subject. We're going in circles beating a dead horse with no more results.
Honestly just stop. The Crucial M4 uses a 4 year old controller... You keep digging yourself a deeper hole with no clear rational. Either you are intentional trying misinform people or you have no idea you are doing it.
Both are equally dangerous.
Stop spreading incorrect information.
