    I hear I should get an app named TRIM Enabler for my SSD. I have a Samsung 840 on a 2012 MacMini Fusion drive. Do I need to enable TRIM even on a fusion drive, or only when the SSD is solo?

    No. The ssd is able to manage. If it doesn't it might be beneficial to use something like TRIM Enabler. Do read up on user experiences though, not everybody benefits from it, some have problems after using it. It's more of a hack which is probably why some people experience problems with it. In this case it depends if Fusion Drive is able to sent out TRIM commands at all.

    Here is an interesting article for you to read:

    Personally I would enable TRIM but I would not use the Trim Enabler by Groths as apparently (and I have not heard or read anything to the contrary), they use a deprecated KEXT to enable trim.

    The Apple KEXT that enables TRIM, does so by checking the firmware of the SSD and looks at the name of the drive that is encoded there. If it reads back APPLE it enables TRIM, if anything else, it does not.

    Other patches work by zeroing out the APPLE string in the KEXT file and thereby enable TRIM support. Or, you can insert the name of your own drive as explained in this thread:

    Either of these are safer than using an out of date KEXT file.

    Apps. like Chameleon SSD Optimizer (see link below) work in a similar fashion and save you the bother of doing things manually:

    I have been using this lately (as opposed to patching the KEXT file manually) and it has worked fine for me.
