evga 680i board raid question

[BigRon]

When installing my 2 drives for raid, do i use 2 primary sata ports or 2 side by side which would be primary then secondary.

Also the port numbers do not seem to corrispond with what the manual says,are they number'd 6 towards top of board working down until 1n2 are piggy backed.

i thought that primary and secondary were a ide thing not a sata.
so there is no performance dif between them then.

I thought there would have been info on jumpering on the board to,but only the basics, Not to impressed with evga board at moment,as it seems i got to rma it now.
