- Differential SCSI is the same speed as normal SCSI, but the cable
- length can be very long. Now, a "fast" SCSI is much faster than
- normal SCSI. It just happens that the HP differential card is also
- "fast". Magneto-Opticals, however, are slow due to physics, not
- any particular SCSI interface. An HP-IB interface could easily
- overdrive an MO disk...
