Are you sure about this "most" rating? Admittedly we're a Gateway-centric shop here, but the machines we have bought from them with IDE CD ROMs not only come with their own IDE controllers, but claim in the documentation that using them on the same controller will result in poor performance. Similarly, the few IDE CD ROMs I have looked at in the store all came with their own IDE controllers.
