Apparently it is for most SSDs, except for the Samsung 840 Pro, which
apparently uses a new technology that conflicts with "discard"
In the event that you are using it, discard it as a test ;-)

How would this effect the 840 Pro with a LUKS encrypted / partition? As
I understand it, discard/trim is useless with encryption.
Where did you get that idea? Provided every layer understands the
discard command, the encryption should make no difference. Are you
perchance confusing discard with overwriting the block with 0s?
