    I know there are a ton of posts about using fsutil query but I also read that it actually doesn't realistically show you whether TRIM is really on or not. I can't seem to download SSD Life because all their mirrors are down.

    Are there any other ways of hardcore proving that its working?

    fsutil behavior query disabledeletenotify

    in command prompt. 0 means it's enabled, 1 disabled.

    Here is a link to an article on Tom`s Hardware, in depth optimizing SSD. Verify trim along with many other tweaks. Check it out


    http://www.tomshardware.com/reviews/ssd-performance-tweak,2911.html


    Verify TRIM:
    •In the Start menu search box, type "cmd" without the quotes
    •Right-click the cmd program and select Run as Administrator
    •In the command line, type "fsutil behavior query DisableDeleteNotify", again without the quotes •if DisableDeleteNotify = 0, then TRIM is enabled
    •If DisableDeleteNotify = 1, then TRIM is disabled

    Guys, this is exactly what I am asking about, I am well aware of the fsutil way of checking, I was wondering if there was any other way.

    To be honest I’m not really sure there is a yes or no answer, only if it’s enabled or not. Reviewers of the drives have to do extensive damage to them, and then use benchmarks to test if trim enabled and working.

    As long as you know it’s enabled and performance remains consistent, you’ll know its working.

    SSD Life (Pro/Trial) program can check it, probably at the same way as command promt method.

    Also, you can track down writes etc. if you need it ofc. But that is pointless for regular users, just set it, and leave it alone.

    "fsutil behavior query disabledeletenotify" does NOT show if TRIM is functional on a SSD. It only shows whether Windows has the TRIM functionality enabled or not. When it's enabled enabled in Windows, it's still up to the storage driver to pass the TRIM command to the SSD. If the storage driver doesn't support it, TRIM will simply not work.

    OP, you might want to try the WinHEX method in Arctucas post. I've tried it to check if TRIM was working on my RAID array. It didn't, as expected on my Z68 board ;)

    But you probably know, that you are able to get TRIM into your Z68 RAID0 array. Look >here<.

    Thank guys, the WinHEX was the thing I was looking for.

    I just had to verify if I got TRIM to truly work with my two 256gig 840 Pro's on X79 chipset. It works yay!

    Thanks for the help!
