Samsung 860 pro / evo - do they report deterministic trim?
Regardless of the kind - DRAT or RZAT. While all the modern ssds should behave in RZAT fashion, quite a few of them don't bother reporting such feature. And some controllers (in my case - old LSI2308 in IT mode) are sensitive in this regard.
In the past, 840 pro reported the feature just fine, 850 pro for whatever reason didn't. Evo line - afaik - never did (even if technically it was(?) supported since at least 850, but I'm not sure).
Thus my question regarding 860 series, as I haven't had any of those under my hands.
