How does 1394 compare to SCSI?
The SCSI bus requires that devices be serially daisy-chained together, with each device having a non-conflicting, pre-assigned address and that the final SCSI device be terminated. There is a limit of seven devices on a SCSI chain. In contrast, 1394 devices can be connected in multiple configurations. These can include a star or tree pattern with its own daisy chain branches. Device terminators are not required. And 1394 addressing, unlike SCSI, is done dynamically; there is no need for address pre-assignment. Plus, 1394 allows up to 1,023 buses to be bridged together.
