I payed only $20 for an external USB optical drive. Mass produced and flimsy. It works fine for ripping cd’s. Just plug it in the usb and it’s recognised. The thing is: it’s noisy. They all are because they spin so fast. That’s fine for ripping because it is done in 5 minutes. But for playing cd’s it is annoying. Also it doesn’t stay in its place. That’s why I taped mine to the side of my rack, out of sight.
That is why the RSA 780 is so expensive. It is the same thing but it has a different function. Playing a cd at single speed is super slow compared to 52x CD-ROM drives but it shouln’t make noise like it’s going to take off. That’s why it has a much thicker case and has some weight so it doesn’t shift or slide.
I think it’s a very good and smart option. A built in cd-drive would destroy the clean look. They often are the first thing to break (always problematical with all in ones) and the extra cost would be the same (only you wouldn’t know, just pay extra).
