    Since i dont really use my SD card slot on my macbook pro, i just read in another thread, that i can use it for readyboost.
    So, how much faster does bootcamp windows 7 get with this Readyboost?
    Also, which type of SDCards will give me the biggest boost? Thank you.

    It really doesn't do much at all. It doesn't really expand the available ram but uses your external storage as a pagefile to prevent paging to the disk whenever you run out of ram.

    If you're running out of RAM (I'm assuming you have at least 4 gigs already) with your typical workload, you will need actual ram to see any improvement. If you don't use your machine heavy enough to utilize all of your ram, you will see 0 improvement as the SD card will never get touched. I did try readyboosting on a Netbook with only 1gb of ram and it was no better or worse off then when I didn't have it.

    IMO: Save the limited read/writes on your SD cards.

    Ditto what c1Phr said. I tried it on my Win 7 PC with 6 gigs of ram installed and saw zero improvement.
