What does IDE (PIO mode 4) represent?

IDE (PIO mode 4) is a legacy CPU-controlled transfer timing mode for ATA/IDE storage devices indicating theoretical throughput values.

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

Converting allows users to compare legacy storage throughput to modern standard data transfer rates for diagnostics, benchmarking, or network planning.

Does the conversion reflect actual effective data transfer speeds?

No, the conversion uses theoretical maximum rates and megabit/second units do not account for protocol overhead or actual user data throughput.
