What does IDE (PIO mode 4) represent in data transfer?

IDE (PIO mode 4) is a CPU-driven programmed input/output timing mode used for ATA/IDE drives, defining how data is transferred rather than a physical storage unit.

Why convert IDE (PIO mode 4) to megabit/second?

Converting to megabit/second provides a widely recognized data transfer rate useful for comparing legacy storage device speeds with modern networking standards.

Is the converted value always accurate for actual transfer speeds?

No, the conversion reflects theoretical maximum throughput. Actual speeds can vary due to hardware limitations, protocol overhead, and system performance.
