I think you mean "512" and "2048" instead of "512k" and "2048k" :-).
(At least you aren't talking about your processor speed in milliHertz!)

RRD40's take non-standard caddies. I'm not sure about RRD42's off the top
of my head.

They're also as slow as molasses. I'd estimate, in modern "X" speed terms,
that a RRD40 is about 0.1X (i.e. if you're lucky you get one sector off
every ten revolutions.)
