Anything SCSI can be used with an Amiga, the only exceptions being HVD and LVD only (LVD/SE works) - the adapters for bridging the electrically different busses are extremely expensive.
Most Amiga SCSI adapters are narrow (50 pin) and some wide SCSI devices require a proper termination of the unused higher byte to work. Everything else is just a matter of finding the correct adapter/cabling.
