IDE controller question

[Dragon]

ok so ive got this dilemma. i want to put 2 or 4 channel PCI ide controller in my comp so i can fit an extra DVDrom or burner and an additional hardrive. i plan on using the firt few thousand sectors of the Hard drive specifically for a page file, and it will be on its own channel, my question is: would it be better to place the new HD on a native IDE channel, or will i have the same performance if i put it on one of the PCI controller channels? because im wondering if there is likely to be any bottlenecking on the PCI bus.
