That's the maximum bandwidth for narrow SCSI-1, used in anything from Mac Plus to 68030 machines. The external SCSI, a separate bus, is always SCSI-1. Sometimes the internal SCSI is SCSI-2 (some 68040 & PPC Macs). WGS95 had a wide SCSI card (so had 3 separate SCSI busses, narrow, fast, and fast wide).
Reportedly, with any of the SCSI emulators, it is not difficult to saturate a narrow SCSI bus with a 68030 Mac, so... it will do exactly 5MB/s on narrow SCSI in these cases.
