What Is This Tool?

This converter allows users to transform values between two legacy IDE data transfer modes: IDE (PIO mode 2) and IDE (UDMA mode 3). It helps in comparing and configuring older hard drive and optical drive timing and throughput settings.

How to Use This Tool?

  • Enter the value in IDE (PIO mode 2) units you want to convert
  • Select IDE (UDMA mode 3) as the target unit
  • Click convert to see the equivalent value in IDE (UDMA mode 3)
  • Use the result to compare or configure legacy drive performance settings

Key Features

  • Supports conversion between IDE (PIO mode 2) and IDE (UDMA mode 3) transfer modes
  • Useful for legacy BIOS, firmware configuration, and vintage PC diagnostics
  • Shows relative transfer rates between CPU-driven and DMA-driven IDE modes
  • Provides quick conversions based on established conversion rate
  • Browser-based and easy to use without installation

Examples

  • 5 IDE (PIO mode 2) converts to 0.83 IDE (UDMA mode 3)
  • 10 IDE (PIO mode 2) converts to 1.66 IDE (UDMA mode 3)

Common Use Cases

  • Configuring transfer modes in BIOS for older PATA/IDE drives
  • Comparing legacy IDE drive timings when restoring vintage PCs
  • Interpreting device driver or benchmark reports on IDE transfer modes
  • Documenting and specifying throughput for legacy IDE hardware
  • Diagnosing performance or compatibility issues related to IDE interface modes

Tips & Best Practices

  • Use the converter to understand relative performance differences between modes
  • Apply results to ensure BIOS or firmware settings are optimized for drive compatibility
  • Remember this tool compares modes and not actual file sizes or transfer durations
  • Consider hardware and system factors that may influence actual throughput
  • Use alongside device documentation for comprehensive legacy system configuration

Limitations

  • Both IDE (PIO mode 2) and IDE (UDMA mode 3) are legacy and slower than modern transfer modes
  • Actual performance depends on hardware condition, BIOS, drivers, and system architecture
  • Conversion shows relative mode rates but does not measure real-time data transfer speed
  • Overhead and system factors can affect effective throughput beyond what conversion indicates

Frequently Asked Questions

What does IDE (PIO mode 2) mean?
It is a legacy ATA/IDE timing mode for CPU-driven data transfers using programmed I/O cycles, mainly on older drives.

How is IDE (UDMA mode 3) different from PIO mode 2?
IDE (UDMA mode 3) uses Ultra DMA for higher transfer rates with less CPU involvement compared to CPU-driven PIO mode 2.

Can I use this converter for modern drives?
No, this tool is designed for legacy PATA/IDE devices and their specific transfer modes, not modern interfaces.

Key Terminology

IDE (PIO mode 2)
An ATA/IDE interface timing specification for CPU-driven data transfers using programmed I/O cycles on older devices.
IDE (UDMA mode 3)
An Ultra DMA transfer mode with minimal CPU intervention, used in legacy Parallel ATA interfaces to improve throughput.
Legacy Technologies
Older hardware or transfer standards no longer mainstream but still used in vintage or diagnostic contexts.
