What does IDE (PIO mode 1) mean in data transfer?

IDE (PIO mode 1) is a CPU-controlled data transfer mode for legacy PATA devices with moderate throughput and higher CPU usage compared to DMA modes.

Why convert IDE (PIO mode 1) to megabyte per second?

Converting to megabyte per second provides a standardized unit to measure and compare data transfer speeds of legacy devices more clearly.

Does this conversion reflect actual continuous transfer speeds?

No, IDE (PIO mode 1) speeds represent CPU-driven bursts and may not reflect continuous sustainable transfer rates.
