What does SCSI (Fast Ultra Wide) represent?

It is a legacy parallel Small Computer System Interface mode with a wider data bus and faster signalling, used mainly for connecting storage devices in older servers and workstations.

What is IDE (UDMA-66)?

IDE (UDMA-66) refers to a Parallel ATA transfer mode with a theoretical maximum raw data rate of 66.7 MB/s, used in older PATA storage devices.

Why convert between SCSI (Fast Ultra Wide) and IDE (UDMA-66)?

Converting helps compare performance and translate data transfer rates between legacy SCSI and IDE systems for compatibility and troubleshooting.

Is the conversion rate exact for real-world use?

No, the conversion reflects maximum theoretical burst rates and does not factor in real-world performance variations.
