What is SCSI (Fast Wide)?

SCSI (Fast Wide) is a SCSI-2 interface mode combining Fast timing with a 16-bit data bus, offering up to 20 MB/s theoretical throughput for legacy hardware.

What does USB stand for and what is its use?

USB stands for Universal Serial Bus, a standard interface for communication and power delivery between computers and a wide range of peripherals.

Why might actual transfer speeds differ from the converted rates?

Real-world speeds depend on factors like cable quality, device negotiation, protocol overhead, and specific USB generation used.
