  4% (1)

Explanation

SCSI ID 8 provides lowest priority while SCSI ID 7 provides highest priority to a device. SCSI IDs determine device priority on a SCSI bus. Narrow SCSI buses that support eight devices use IDs 0 to 7, while wide SCSI buses that support 16 devices use IDs 0 to 15. Higher ID numbers have higher priority. SCSI IDs are split into two groups, with numbers 0 to 7 having priority over 8 to 15. Therefore, SCSI ID 7 has the highest priority. The ID priority order on a SCSI bus is as follows: 7, 6, 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8. The SCSI ID assigned to a device on a SCSI bus can be important to the performance of a computer because IDs dictate the priority in which a device gets access to the bus.
