Hi,

I'll second the idea that random ide disks work just fine, at least
as slaves.

People keep pushing SCSI disks in Ultra 5 and 10s, but, are they
really faster?  My ultra 10 with some random (and I do mean random)
cheap ide disk is faster doing disk i/o then almost anything else I
have at home and competitive with the faster (cpu wise) ultra 2 with
very fast scsi disks.  Would it be all that much faster if I had 
scsi disks then?

thanks

cheers

bruce
