The way I interpret a few technical papers I've read is that because of the technical characteristics of IDE it is not possible to read and write simultaneously on the same IDE cable/port. Putting 2 HDs on the same cable therefore gains absolutely nothing if one is transferring data between them - which is why I put my HDs as masters on the 2 IDE ports with the CDROMs/DVDRWs/CDRWs as slaves.
If you do speed tests on them using hdparm you will probably see they are quite slower that way - unless you are lucky. Experimenting is definite, theory is not.
About your first question:

Further to my earlier response, I've now looked at this How-To and I can't see anything there to contradict what I said. The How-To talks about removing another device from the same cable to be able to install another drive (to copy the system from 1 drive to the new one) but this is in the context, the way I read it, that the controller is supporting 2 EIDE devices. The article is also written some 4 years ago (2000). I haven't read the article re hdparm so haven't yet done any practical testing. Cheers. -- I am not young enough to know everything.
