Does 1394 (FireWire) replace SCSI?
For many users and application, yes! Like SCSI, FireWire is a high-speed protocol. But SCSI devices require they be daisy chained in a line one after another. You cannot “Hot-Swap” SCSI devices without risking damage, and unique Ids and terminators are required. FireWire chains can be set up in a much more flexible topology. You can plug-in more devices with FireWire, extend them for longer distances and connect / disconnect them in real time. Some new computers have been released without SCSI ports in favor of a 1394 (FireWire) interface.
