I think you shouldn't worry too much an either disable NCQ or remove the discard option from fstab. I will not speculate on the performance impact of disabling NCQ. Please take your favorite I/O benchmark and evaluate the different options.
I saw patches that add an option to only disable queued TRIM and leave NCQ enabled for everything else. But they will only show up in Linux 4.1, as far as I know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1449005 Title: trim does not work with Samsung 840 EVO after firmware update (EXT0DB6Q) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fstrim/+bug/1449005/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
