Hmmm, that's surprising, since my current development system uses
a Quantum Atlas (though its the XP32150S, the 2GB version). This 
drive worked with the NCR driver of Spring 1995 at least, when I 
first tested it.

I'm quite sure that the Adaptec 1542 supported it as well, since
it is hard to find a device that doesn't work on the Adpatec, and
the Atlas is really well designed (IMHO).

The Quantum Grand-Prix (XP34301S) is a different beast. It has got 
bad press because of many failed (or DOA) drives, and it is noisy 
and significantly slower than the Atlas, though both are 7200RPM
drives.

You may also want to have a look at the IBM DHFS series, which is 
also very fast and AFAIK reliable.

Can't comment on recent Seagate drives.
