    I've heard that SSDs do not function as fast in bootcamp Windows 7 compared to running in Mac OS X. Is this still true?

    Thanks

    You've heard wrong. This was never true. :confused:

    Windows 7 runs lightning fast in bootcamp, *especially* with an SSD.

    hmm it was just that I heard SSDs did not run in AHCI mode (like they do in OS X) and thus the read and write speeds are slower.

    This used to be the case, but from 2011 models onwards I believe they now operate in AHCI.

    Certainly 2012 RMBP does. I can't recall for sure if my 2011 model did, but I think it did.

    Mac mini 2010 server and Mac mini 2011: Intel X25M-G2 and pulled Toshiba SSD from a Macbook Pro (2011) run just as fast in non-AHCI as in AHCI.

    Samsung 830: A big difference between AHCI and non-AHCI.

    In order to run in AHCI you have to do some juggling in Terminal and make some changes in the windows registry.

    The above is for Windows 7 - I do not know about Windows 8.

    Just as a reference point - the OEM 512GB SSD in my 2012 Mac Pro scores a 7.2 on the WEI in Windows 7 x64 Enterprise. Which is nowhere near where the SATA3 would get a 7.9, but it is still very fast. Machine is very fast and responsive, and TRIM is enabled automatically by Windows 7.

    When Boot Camp 5.0 was released for 2011 models, the support software included updated logic board chipset drivers that installed in AHCI mode.
