Hence why I said it's rated at 3Gb/s

If you installed the driver during initial setup you should be ok. If you try to switch from IDE to AHCI after you install, you'll have to do some driver hacking on system files, which is tedious and you might as well just reinstall Windows, as it will be easier. I've done it, and wasn't really worth the time I spent IMO. Woulda been easier to just reinstall.
