Best SATA drive setup? Use ICH9R or Gigabyte SATA Controller?

The parts:

Gigabyte motherboard # GA-P35-DS4
The MB has two different SATA controllers.
It has an Intel SATA controller ICH9R with 6 SATA connectors
(ports)
and a Gigabyte SATA drive controller with 2 SATA
connectors(ports)

I have 2 SATA hard drives. (not to used in RAID)
and 1 SATA DVD-RW drive.

I thought I read somewhere that the Intel ICH9R controller
would perform better than the Gigabyte controller. Is that
true?

Would it make any performance difference what drive is used
in what controller or port?

For example should I use the Intel controller for the hard
drives and the Gigabyte controller for the DVD to separate
the loads?

Thanks,
Lou
