Why convert from IDE (UDMA mode 4) to IDE (PIO mode 0)?

This conversion aids in comparing data transfer rates for legacy hardware compatibility, troubleshooting, and BIOS configuration of older ATA devices.

What does IDE (PIO mode 0) represent in ATA standards?

IDE (PIO mode 0) is a slow, CPU-driven data transfer mode used for compatibility with very old drives and controllers.

Can this conversion reflect real-world data transfer speeds?

No, the conversion relates to theoretical maximum throughputs and actual performance depends on hardware and system factors.
