Yeah, you can technically get better performance if you have as many 
drives as possible on their own separate ide channel, instead of using 
slaves, so if the system wants access to them at the same time it can 
get it.

Of course how far you can go with this ideal depends on how many devices 
you want to accomodate, and how many ide channels you have free. I have 
my swapfile on a different disk on its own channel w/ no slave; but I 
guess depending on what the devices are and how you use the system, for 
some people not having slaves could be performance beneficial, whilst 
others might not really care/notice and could prefer an extra drive 
attachment.
