Hans,
But there is a large number of users which is still reporting issues with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or Marvell SATA controllers and all reporters also report these problems going away when disabling queued trims.
I originally tested queued trim with 860 drives and never had an issue on my systems. But no objections wrt. turning it off.
