I have 2 DVD writers Optiarc AD-7200a and 2 ATA/133 hard drives.
How should I connect them to the two IDE channels so that I get the most optimal throughput when simultaneously ripping DVDs to hard disks (each DVD drives to each hard drives).
Connect the hard drives to each other on one channel, using cable select or master/slave, and do the same with the optical drives. The key to remember is to always put devices that are the same with each other. Don’t mix them.
