Dear LazyWeb: should I be running my 500GB SATA-II drive in IDE or AHCI mode?

FWIW, I installed with IDE. Found a registry setting that allows you to switch to AHCI mode after installing (HKLM\System\CurrentControlSet\Services\msachi\Start needs to be 0 for AHCI to be active, it seems) and I already tried that out… I still have my SATA DVD drive showing up there (some people lost theirs when they tried this) so that’s a non-issue.

My reason for asking is that I’ve read that AHCI mode is supposed to be better yet I think IDE mode was faster – or at least I’m seeing AHCI take longer on boot and then hiccup a little bit while booting…

Just curious…
