What is IDE (PIO mode 0)?

IDE (PIO mode 0) is the slowest CPU-driven ATA transfer mode where the host reads and writes device registers while waiting for readiness signals, mainly used for compatibility with very old drives.

Why convert IDE (PIO mode 0) to IDE (PIO mode 1)?

Converting helps compare transfer speeds between legacy PIO modes for diagnostics, benchmarking, and firmware development on vintage or embedded systems.

Are these PIO modes suitable for modern storage performance?

No, both PIO modes have high CPU overhead and limited throughput, making them unsuitable for contemporary high-speed data transfer requirements.
