What does SCSI (Fast Ultra Wide) represent?

It is a parallel Small Computer System Interface mode that uses a wider data bus and faster signaling for higher throughput in legacy storage devices.

Why use IDE (PIO mode 0) as a reference?

IDE (PIO mode 0) defines the slowest CPU-driven data transfer mode for old drives, useful for compatibility with very old hardware.

Can this tool measure actual device speed?

No, the tool offers theoretical conversion based on maximum data transfer rates, not accounting for real device performance factors.

Key Terminology

SCSI (Fast Ultra Wide): A legacy parallel Small Computer System Interface mode with a 16-bit bus and faster signaling for improved data transfer rates.
IDE (PIO mode 0): An ATA/IDE programmed input/output timing mode where data transfer is CPU-driven without DMA, resulting in lower throughput.
Data Transfer Rate: The speed at which data is transmitted between a storage device and a host interface.
