What does SCSI (Fast Ultra) refer to?

SCSI (Fast Ultra) is a parallel SCSI signalling mode combining Fast and Ultra extensions to improve device-to-host throughput and reduce latency while maintaining compatibility with the SCSI command set.

What is IDE (PIO mode 2)?

IDE (PIO mode 2) is an ATA/IDE interface timing specification for programmed input/output data transfers typically used by older IDE drives to manage data movement without direct memory access.

Why convert from SCSI (Fast Ultra) to IDE (PIO mode 2)?

Conversions help compare or translate transfer speeds between modern SCSI modes and legacy IDE standards, especially useful in mixed technology environments or when troubleshooting older systems.
