Interrupts are unimportant nowadays. It is much more important how the
on-board controller is connected to the rest of the chipset internally.
You should not have problems with the controller integrated into the
chipset, but if you also have a secondary controller (so >= 8 ports in
total) then it may only be connected by a single PCI bus internally, and
that is not enough to drive all the disks simultaneously.

SATA drives have dedicated cabling so it does not matter where you
connect them.
