    Just upgraded to an Intel 320 SSD and am running 10.7 and Windows 7 x64 (via Bootcamp). My initial impression is that both operating systems run fast and efficiently with an SSD. Lion boots faster than Windows 7 for me, but following boot, it appears that Windows 7 seems much faster and zippier than Lion.

    Does this have anything to do with the TRIM support in Windows 7? I do have the TRIM hack enabled in Lion and after installing it my xbench score went from 260 to 280.

    I am sure that both are great, but do bear in mind that Lion is still a beta so I am not surprised that it isn't as fast as it might be yet.

    Lack of TRIM shouldn't make a difference in the short term. As the drive gets "dirty" across all blocks is when you would see a difference. I also suspect the autosave & versions on Lion are going to do a good job of dirtying the SSDs A LOT faster than otherwise would have which is going to make it even more imperative to have TRIM.
