Hard drive mode: IDE or AHCI?

  1. Hi, I just want to know what the best mode is, IDE or AHCI, my board has defaulted to IDE so that's what I'm currently using.

    Thanks

    If it's an SSD then you should change it to AHCI and reinstall Windows. If all of your drives are normal HDDs then it won't make any difference.

    I have windows on an ssd, I have a hybrid, and some regular drives.

    Should I still change it and reinstall?

    Yes, at the moment you're not getting the best out of your SSD. IDE is legacy now.

    I've never tried it but is my understanding that if you're running Windows 7 or Vista you don't need to do a full reinstall to switch to AHCI. See here http://support.microsoft.com/kb/922976

    The above works.

    Cool, I assume this will increase the speed of the drive?

    In a way, yes.
