What does SCSI (Ultra-3) refer to?

It is a version of the Small Computer System Interface standard describing parallel storage interfaces for block-level data transfer between hosts and devices.

What is IDE (UDMA mode 0)?

This is the Ultra DMA mode 0 transfer standard for Parallel ATA devices that defines timing and a typical maximum raw data transfer rate of about 16.7 MB/s.

Why convert SCSI (Ultra-3) to IDE (UDMA mode 0)?

Conversion helps compare or translate data transfer rates between legacy parallel SCSI systems and PATA/IDE devices for diagnostics, benchmarking, and compatibility evaluations.
