I am using an Asus P5W64 WS 975X board. It suggests that the boot drive be on one of the 2 master SATA ports (I am using IDE, not Intel Matrix Raid). My question is this: I have a second hard drive that I back up to, copy from the boot drive, etc. Some of these files are large video files. Am I better off having the second storage drive as the "slave" on the SAME IDE channel as my C: drive, or should the second storage drive be the "master" on the second IDE channel? Both run UDMA 6, PIO 4, SATA II, etc. Thanks for any help.
