raid group on same bus/enclosure

is it better to create the raid group on different bus/enclosure or same bus/enclosure? do I get better performance using disks spread out on different bus/enclosure?

Not a very VMware related question. Better move to another forum.

But long answer short, you will not have any performance benefit that worth the trouble
