ultra160 with ultra320 on same SCSI card.

I have a NT server with a SCSI card installed, which is running perfectly at the moment.
The SCSI card has 3 slots, 1off 50pin slot and 2off 64pin slots. The 50pin slot goes to a tape drive, which works and one of the 64pin slots goes to 2 Ultra160 hard drives which work
I need to add a couple more hard drives and all my supplier has on he shelf is Ultra320 which he says I cannot mix on the same cable/card as the Ultra160 drives.

First question, is he correct saying I cannot mix 160 and 320 on one cable?

Second question, can I add 2 new Ultra320's to the same card using the second free 64pin slot, keeping the existing Ultra160's on the first 64pin slot.

No, he is not correct... an Ultra320 drive works just fine on a Ultra160 card/cable.  (the drive will detect its host and "downshift" into the Ultra160 mode)

Yes, you can them to the same card (in fact, you could even add them to the same cable as your existing devices on the other 64-pin port)
