Is there a benefit of putting a software raid array on separate channels? For example, I have two built in IDE controller ports, and then with the addition of the Promise 133, I will have two more. Will I see significantly more performance if I setup the software raid 5 as follows: C1 Master - OS disk C1 Slave - RAID disk 1 C2 Master - CD-ROM C2 Slave - RAID disk 2 C3 Master - C3 Slave - RAID disk 3 C4 Master - C4 Slave - RAID disk 4 Where the raid array disks are all on separate "channels" or can I stack them as such (will be much easier to setup): C1 Master - OS disk C1 Slave - CD-ROM C2 Master - RAID disk 1 C2 Slave - RAID disk 2 C3 Master - RAID disk 3 C3 Slave - RAID disk 4 C4 Master - C4 Slave - My assumption is that if they are on separate channels I should see a significant performance benefit, but I am unsure. Keep in mind that the controllers are a built on motherboard controller (probably cheap), and a cheap Promise 133 PCI add on card. Has anyone done or seen some performance tests to see if this has any noticeable performance benefits?
