Is Ultra 160 SCSI better than EIDE?
The answer depends on the application. SCSI is an intelligent interface that can perform data transfers with no intervention from the host CPU. SCSI is multi-tasking. An initiator can issue a command to a target. The target can then disconnect from the bus to perform the task and free the bus up for another task. Ultra 160 SCSI can have up to 16 devices connected to the bus and they can be any of a large variety of peripherals, including hard drives, floppy drives, tapes, CDs, scanners, printers, etc. The number of devices can be substantially increased through the use of LUNs. EIDE can have two internal drives connected. Your PC probably has two EIDE buses, so it may have up to four peripherals. Ultra 160 SCSI allows up to 12 m (40 ft) of cabling, which may be internal or external to the computer. For point to point applications you may have up to 25 m (82 ft) of cable. EIDE is for internal cabling only and the maximum cable length is only 18 inches. And, don’t forget that 160 Mbytes/
