    There is no need to specify noatime and nodiratime.

    Just using noatime implicitly specifies nodiratime as well.

    Spookily enough I was reading an article this evening which was saying the same, I hadnt realised it was a subset, but i am finding conflicting information.

    I am still looking into it, but cheers.

    You may want to look here where someone looks at the source code.

    Rubbish, the code for "Discard" has been in the kernel for Swap partition processing for a while now. It is always used and is not a user option.

    Interesting.

    However it appears on the arch and debian wiki that it is a user option however ?

    That being said Swap shouldnt be on a SSD where possible though which was my point, as for swap not being able to use it, i wasn't aware it could but it would appear that the user can define it.
