I've just installed the Ubuntu Raring (with Sandisk Extreme) and I know there're multiple articles over the internet (and here) about TRIM, but I suspect it's a native resource on Ubuntu Raring.
PS: Tried to find something in the Ubuntu's documentation, but did not.
Then I've read lots (and lots) of articles and all of them providing different ways to enable TRIM (fstab, cron job, init scripts, etc ..).
And I got something interesting -> I've performed those tests (creating testfile / removing / running hdparm) WITHOUT "discard" in the /etc/fstab and I got that same results, I got those expected "zeros" output.
That suggested TRIM test I've uploaded (just in case), http://www.pasteall.org/43964/text
That's why I'm wondering -> Is the TRIM active by default on Ubuntu Raring?
If not .. any recommended way to active it, among so much options? Thx.
PS: This is not the same question as the duplicated one. Here I'm trying to understand the NATIVE trim support (as it looks like)
