Subject: HP-IB or SCSI disks for a 300 series?

A reasonably reliable friend of mine (who works at HP) commented to
me that he thought SCSI disks on a 300 have approximately the same 
performance as HP-IB disks; the performance characteristics of the 
disks are a function of a number of different factors (including the 
speed of the disk, the controller board, the bus speed, and the
processor speed, as well as the interface speed) and that in fact if
I were to go from HP-IB disks to SCSI disks I wouldn't necessarily 
see any sort of performance improvement.

I found that a bit surprising, but somehow it *does* have the ring
of validity, so ... what's the gig?  Is this true?  Will a fast HP-IB
disk perform as well as a fast SCSI disk?

If that's the case, then what's the fastest, most reliable, HP-IB 
disk available today, from HP or otherwise?  What's it list for?  
(300 MB and up only; dinky disks aren't worth the power requirements
on my system, I think)

	Thanks for any input on this question!
