    Not that I am aware of no but am hopeful that OS X Lion. TRIM would be handy / helpful etc

    Have spoken to various Apple technical people about this subject it unlikely that Mac OS X will ever require the TRIM command....below is a review of ssd performance on Macs

    If it does happen it's not likely to be until Mac OS X 10.7

    We may find out if Lion supports TRIM quite soon...

    Based on all that I have read about it the Mac OSX file system does not actually need the TRIM command as it handles that without needing a hardware solution.

    As much as I hate to say it this is an area that Apple is ahead on, NTFS is quite an old filesystem which has been upgraded a bit over the years but does not seem to have kept up with some of the alternatives meaning that things like TRIM are nessisary.

    It looks like Lion does indeed support TRIM. However, in typical Apple fashion it is only enabled for their own SSDs.

    Prise en charge de TRIM = Oui

    Both Microsoft and Apple could improve their file-systems IMO. Neither of them have anything like ZFS.

    Someone has found a way to enable TRIM for non-Apple SSDs.

    There's now an app for that ^

    TRIM support is coming in OS 10.7 Lion, but if you’re running Snow Leopard right now you can enable it with TRIM Enabler, which performs a little hack on your system that lets you take advantage of TRIM. (Source)
