You're confusing SCSI-3 (protocol) with connectors, although there is
some relation, it's not really a problem.  The scsi protocol is backward
compatible, so that a SCSI-3 device will work with a SCSI-1 controller.

What you're really concerned about here is the interface for connecting
that particular drive up.

Most manufacturers are putting out ultra-wide disks at presnt (68 pin),
but you can still get the new disks with narrow (50 pin) interfaces and
for boxes such as the SS5/SS20, you need the SCA interface (80 pin).
