What does IDE (PIO mode 2) mean?

It is a legacy ATA/IDE timing mode that uses programmed input/output cycles for CPU-driven data transfers with older storage devices.

Why convert IDE (PIO mode 2) to IDE (UDMA mode 0)?

To compare and understand differences in data transfer rates between older programmed I/O timing and newer Ultra DMA protocols affecting device performance.

Can this tool guarantee exact real-world transfer speeds?

No, since conversion assumes ideal conditions. Actual throughput varies due to hardware and configuration factors.

Tips & Best Practices

Use this converter to compare relative performance rather than exact data size equivalence.
Be aware that real-world performance can differ depending on hardware and system conditions.
Check BIOS and driver settings carefully when diagnosing device transfer speeds.
Use conversion results to aid in troubleshooting and upgrading legacy hardware.
Keep in mind that PIO and UDMA represent different transfer mechanisms with varying efficiencies.

Limitations

Conversion relies on ideal nominal speeds and may not reflect actual throughput.
Differences in hardware condition, cable quality, and system setup impact real-world speeds.
PIO and UDMA modes operate under different transfer protocols, making direct data size comparison inaccurate.
This tool is intended for understanding and comparing relative transfer rates, not exact byte-for-byte conversion.
