[CentOS] Software RAID: on same IDE port or on different ones?

I have a general question on software RAID performance. If using two IDE 
disks on RAID 1: is there much of a difference performancewise if I put 
both on one IDE port as master and slave or should I better put them on 
seperate ports. I remember from olde days that it was recommended to put 
CD and hard disk on different ports to maximize the throughput between 
them and as RAID1 is theoretically writing to both disks at the same time 
I guess putting them on different ports might be an advantage. Is it one 
or is it negligible?
