    So- I have windows installed as bootcamp. Just bought parallels so that I can access it from within OS X. Does OS X's TRIM cover this or do I need to enable it specially in windows? I would think OS X actually doesn't cover it since it still access a real hard drive.

    Also, if I boot into bootcamp, is TRIM there natively?

    This is entirely dependent on the drivers on Windows support for TRIM.

    For which? Parallels or boot camp? I'm more concerned with parallels but would like to know both.

    On the Boot Camp side of things. (Note: You are not required to use Apple's full driver set in many cases.)

    So if I'm using parallels, but I didn't import the bootcamp, is it still accessing the bootcamp partition? I would assume so, so TRIM is enabled for that part?

    No, the Boot Camp partition is not used in that case, which means TRIM support will come from OSX.

    Really? I don't think thats so. I looked in the parallels folder in my docs and its only 6.53 MB. Pretty sure it still access the hard drive.

    You said you didn't import Boot Camp.

    Sorry maybe I wasn't clear.

    There are I guess three options.

    -Create new windows install
    -Import windows bootcamp, basically copying it over and making it all virtual
    -simply accessing the bootcamp partition that exists right now

    Does that make sense?

    Ahh, I follow you now. In this particular case, though it is using the Boot Camp partition as the basis of your Parallels virtual machine, TRIM support is still provided by OSX.

    The ONLY case where TRIM is provided by Windows is when booted into Windows.

    Yes. The reason is that the host OS always provides the drivers for hardware, regardless of virtual OS / partition setup.
