Why convert from USB to IDE (PIO mode 0)?

This conversion helps compare or adapt data rates between modern USB devices and old IDE storage drives that use the slow PIO mode 0 for compatibility, diagnostics, or data recovery.

Does this tool reflect actual transfer speeds?

The tool provides theoretical maximum throughput rates and may not perfectly represent real-world speeds due to hardware and protocol differences.

Can I use this conversion for embedded systems?

Yes, it is useful for simple embedded or low-cost systems that rely on CPU-driven ATA transfers without DMA support.

What Is This Tool?

This tool enables conversion of data transfer rates from USB, a modern serial interface for communication and power, to IDE (PIO mode 0), an older CPU-driven data transfer mode used for legacy storage devices. The converter helps compare or adapt transfer speeds between these distinct technologies.

How to Use This Tool?

Enter the data transfer rate value in USB units.
Select USB as the from-unit and IDE (PIO mode 0) as the to-unit.
Click convert to see the equivalent transfer rate in IDE (PIO mode 0).
Review the results considering the theoretical nature of the conversion.

Key Features

Browser-based interface for quick, easy access.
Includes use cases for vintage hardware compatibility and embedded systems.

Examples

1 USB is approximately equal to 0.45 IDE (PIO mode 0).
10 USB units convert to about 4.55 IDE (PIO mode 0) units.

Common Use Cases

Comparing transfer speeds between USB devices and old IDE drives.
Data recovery and diagnostics on vintage computers using IDE (PIO mode 0).
Integrating modern USB peripherals with legacy ATA storage systems.
Supporting embedded systems lacking DMA capabilities using CPU-driven transfers.

Tips & Best Practices

Understand that USB rates depend on the specific USB version in use.
Use the conversion as a theoretical guide rather than an exact speed match.
Consider hardware and firmware constraints when applying conversion results.
Validate compatibility in legacy systems before relying on converted values.

Limitations

Conversion assumes a nominal USB data rate, which varies by USB generation.
IDE (PIO mode 0) is limited by CPU timing and cannot reach USB throughput.
Actual speeds may differ due to protocol overhead and device conditions.
