What is the best option to have a raid 5 array with 3 disks in the six channel Intel ICH10R controller? On channel 1, 3 and 5. Channel 1, 2 and 3 etc...
Or doesnt this matter on the performance?
Does not matter, using ctrl+I to enter the Intel option rom raid configuration utility to choose hard drives to be included in the raid 5 array, any other ports/drives will operate independently of the raid array and will not interfere with performance.
