What does SCSI (Fast Ultra) refer to?

It refers to parallel SCSI signalling modes combining Fast and Ultra extensions to improve throughput and reduce latency while maintaining compatibility with the SCSI command set.

What is the main characteristic of SCSI (Ultra-2)?

SCSI (Ultra-2) employs Low Voltage Differential signalling to enable higher data-transfer performance and longer cable lengths than earlier SCSI variants.

Can I directly replace devices between SCSI (Fast Ultra) and SCSI (Ultra-2)?

No, because of differences in electrical signaling and hardware requirements, direct substitution may not be possible without appropriate hardware support.
