Internal Laptop HDD vs External - Q bout performance

[KHRZ]

It's faster than loading from discs on a real wii, however, games like SSBB which has a 20 second loading time from a wii disc before the game begins, still has 10+ seconds of loading from a drive, while in Dolphin from your main PC drive, there's no loading at all. So loading is slower but performance shouldn't suffer.
