Most common SCSI Standards - Specifications
| Mode | Bandwith | Frequ. | Max Data Transfer Rate |
Max Cable Length Single- -Ended |
|---|---|---|---|---|
| SCSI-I | 8-bit | 5 MHz | 5 MBps | 6 meters |
| SCSI-II | 8-bit | 5 MHz | 5 MBps | 6 meters |
| Fast SCSI | 8-bit | 10 MHz | 10 MBps | 3 meters |
| Wide SCSI | 16-bit | 5 MHz | 10 MBps | 6 meters |
| Fast/Wide SCSI | 16-bit | 10 MHz | 20 MBps | 3 meters |
| 32-bit SCSI | 32-bit | 5 MHz | 20 MBps | 6 meters |
| 32-bit Fast SCSI | 32-bit | 10 MHz | 40 MBps | 3 meters |
| Fast-20 SCSI | 8-bit | 20 MHz | 20 MBps | 1.5 m |
| Fast-20 Wide SCSI (UltraSCSI) |
16-bit | 20 MHz | 40 MBps | 1.5 m |
NOTE: Fast-20 Wide SCSI is also reffered to as UltraSCSI single ended. The single ended refers to the length of the SCSI cable w/o using differential technology and w/o the use of a SCSI repeater.
With an SCAM (SCSI Configured AutoMagically) Adapter installed, the adapter
use ID #6 during BOOT. All to an SCAM-adapter connected devices should support SCAM - otherwise conflicts.
