EXS 24 Logic Sampler Users Group

Hi all.
Advice needed.
I have 3 hd's on my computer.
My main audio programs (Logic V5) Wavelab, ect, are on IDE channel 1 
on motherboard.
My r/w ide cd rom is on IDE channel 2 on the motherboard.
My audio files are on a seperate drive on a ide controller card.
My downloads and MP3's are on another seperate drive on the ide 
controller card.
My question is where is it best to keep the EX samples folder??
In the Logic folder? or on another drive?
Will it help to have it on another drive? or is it best to leave it 
in the Logic folder?
Any advice would be appreciated.
Allan.
