 If there is a driver for a rodime drive then presumably the interface
 is ST506 compatible.  I have a Rodime 40mb drive and have been very
 happy with it; it has been running for almost 2 years now without a
 hitch and has ~50ms average access.  If I was to get another drive
 though I think I would go for one of the 30ms avg. acc. drives like
 a Maxtor - keeping it in a separate box if it wasn't half height
 (the Rodime drives aren't) wouldn't be as neat but it's a small price
 to pay for increased performance.  This brings me to the questions
 I wanted to ask:
 
 1. does the 7300 use an ST506 interface?
    if not, is it any known standard?
 
 2. can one just get longer cabling and hang a second
    (external) drive on the system
 
 3. if you did add a second (faster) drive how hard would
    it be to make the system page from the faster drive
    instead of the original.

 Thanks in advance,
