    Hi, I'm sorry I know that I can probably find all the information somewhere here, but I'm really confused with all the different information I see around on the web and I just got a SXPS 1647 replacement with this SSD drive so...

    What's the current status? Does or doesn't it support TRIM and if then with which firmware?

    Thank you very much...

    I've read in some of the threats, that someone got his SSD replaced because of missing TRIM support. So I would advise you to contact Dell support and ask them for replacement or instructions on how to enable TRIM.

    Download CrystalDiskInfo, it will tell you if your drive supports TRIM.

    I saw somebody say that it just tells you that it's supported but that it doesn't mean that it's actually working and so on...

    IDK what's up with these shenanigans. TRIM is enabled, or so says, CrystalDiskInfo.

    But this is new:

    And this is now:

    I have no idea what to think.

    Your speeds are basically the same, what is the problem?

    Sequential Writes....from 168MB/s to 69MB/s.....I'd say there was a difference.

    Sorry missed the "1". When I got my Dell Outlet XPS16 the SSD speeds were lacking a bit. I had to do a Secure Erase to get it back to where it should be.

    Do you have TRIM? How long have you used it?

    No problem; I didn't see it at first either, lol. :)

    Check your driver for your hard drive. I played with all of the options and they all gave me different speeds.

    Yes I have TRIM. I've only used it about 3 weeks. I did a few SSD tweaks from a forum on this thread. Disable defrag, disable system restore, disable indexing, etc.

    Hm, strange. Here are the results from mine:

    [​IMG]

    The I used the Intel SSD toolbox to optimize it and here are the results:

    [​IMG]

    Intel SSD toolbox optimization should do what actually TRIM is supposed for. All software say TRIM is enabled, but is it indeed or Win7 fails here. Do not know.

    Thanks. It seems my drive is just having a bit of an issue, nothing permanent. Someone recommended I do a "secure erase" and then it should be good. :D

    @06voy

    I tried MSAHCI and Intel's new Rapid Storage Technology thing. MSAHCI gave me marginally better scores.

    Still really annoying. Makes me wonder if these synthetic benchmarks are showing false claims, or if SSD speed truly drops as you use it more. Having to do a "secure erase" every so often almost negates the benefits of SSD. If you're using Windows 7 you could create a system image, do the secure erase, then reinstall with the backup. This may save you a lot of time if you have a lot of files and programs installed.

    It is super annoying....but, like I said, this should not be happening as the drive does have TRIM. IDK what's up.

    No, it's actually legit real. I've seen reviews which show a real drop in performance, particularly in copying large files after you've used the drive extensively.

    Yeah, that's one good thing about having a Blu-ray writer: image backups on a single disk. And the Windows' image files have fantastic compression. 50GB full on the hard drive to about 28GB used on the Blu-ray disk. And I'm hoping that it keeps the alignment. Last time I did, it seems to retain the alignment in the backup. We'll see if I was just lucky. :D

    Wait so you are saying that although TRIM is probably "working" you notice a major slowdown? Is it a widespread problem?

    @headHunter

    TRIM is not functioning. Note the slow write speeds. If TRIM was working, my write speeds would be normal (normal = 165-180MB/s). Why it isn't functioning: no idea.

    On a total side note, I have not felt a single slow down, despite the slow write speeds.
