What Is This Tool?

This tool allows users to convert data transfer values from IDE (PIO mode 0), a CPU-driven ATA timing mode for legacy devices, to IDE (UDMA mode 4), a faster Ultra DMA transfer mode with higher throughput. It is designed to assist with understanding and comparing transfer speeds between these standards.

How to Use This Tool?

  • Enter the desired value in IDE (PIO mode 0) units
  • Select IDE (PIO mode 0) as the source unit and IDE (UDMA mode 4) as the target unit
  • Click convert to see the equivalent data transfer value in IDE (UDMA mode 4)

Key Features

  • Converts values between IDE (PIO mode 0) and IDE (UDMA mode 4) data transfer rates
  • Browser-based and easy to use with a clean interface
  • Includes context and use cases relevant to legacy and embedded systems

Examples

  • Converting 10 IDE (PIO mode 0) yields 0.5 IDE (UDMA mode 4)
  • Converting 20 IDE (PIO mode 0) yields 1 IDE (UDMA mode 4)

Common Use Cases

  • Connecting legacy IDE drives in old PCs that only support PIO modes
  • Configuring or troubleshooting DMA modes in BIOS or firmware for older hardware
  • Benchmarking or maintaining vintage storage devices and recovering data

Tips & Best Practices

  • Ensure your hardware supports the required 80-conductor IDE cable for UDMA mode 4
  • Use this tool for theoretical conversion; verify real-world performance with hardware tests
  • Reference the converter when upgrading or comparing legacy drive configurations

Limitations

  • Conversion values reflect theoretical maximum speeds and do not include real-world overhead
  • Effectiveness depends on hardware and firmware capability to handle UDMA transfers
  • Physical cable and device quality can affect actual data transfer performance

Frequently Asked Questions

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

Why use IDE (UDMA mode 4)?
IDE (UDMA mode 4) offers much faster block data transfer using Ultra DMA at a maximum theoretical speed around 66.7 MB/s, requiring an 80-conductor IDE cable.

Can this conversion reflect real device speeds?
No, the conversion shows theoretical maximum rates and does not account for real-world factors like hardware condition or overhead.

Key Terminology

IDE (PIO mode 0)
A slow ATA Programmed Input/Output timing mode where data transfer is CPU-driven and compatibility is prioritized for old devices.
IDE (UDMA mode 4)
A faster Parallel ATA transfer mode using Ultra DMA protocol with a higher maximum theoretical throughput requiring specific cabling.
Ultra DMA
A data transfer protocol used in IDE (UDMA mode 4) that moves blocks of data efficiently between host and storage device.
