I have an Adaptec 3940UW controller in a machine. The 3940UW has two SCSI busses on it. Originally, I had two Quantum XP34550W drives on bus A and a Jaz drive and a CDROM drive on bus B. I got sick of the Jaz drive and CDROM (I never used them anyway) so I removed them. Is there any reason to (or not to) move one of the Quantum's onto bus B? I suspect it is important to observe that I do not copy data between the two drives very often.
