What Is This Tool?

This tool helps you convert data transfer rates between two legacy Parallel ATA (PATA/IDE) Ultra DMA modes: IDE (UDMA mode 3) and IDE (UDMA mode 2). It aids in understanding and comparing theoretical maximum throughput as well as configuring or troubleshooting PATA/IDE storage devices.

How to Use This Tool?

  • Enter the data transfer value in IDE (UDMA mode 3) units.
  • Select IDE (UDMA mode 2) as the target unit for conversion.
  • Click the convert button to obtain the equivalent data transfer rate in IDE (UDMA mode 2).
  • Use the result to assist with legacy hardware compatibility and performance analysis.

Key Features

  • Converts between IDE (UDMA mode 3) and IDE (UDMA mode 2) units for data transfer rates.
  • Shows theoretical maximum transfer rate comparisons for legacy PATA/IDE interfaces.
  • Supports use cases in system configuration, benchmarking, and troubleshooting.
  • Browser-based and easy to use with clear input and output units.

Examples

  • 1 IDE (UDMA mode 3) equals approximately 1.515 IDE (UDMA mode 2).
  • 2 IDE (UDMA mode 3) equals approximately 3.03 IDE (UDMA mode 2).

Common Use Cases

  • Specifying or comparing throughput for legacy PATA/IDE hard drives and optical drives.
  • Configuring BIOS or drive firmware settings on older PCs to ensure compatibility and performance.
  • Interpreting benchmarking and troubleshooting results of systems using PATA/IDE storage.
  • Refurbishing legacy computer systems with accurate data transfer mode settings.

Tips & Best Practices

  • Verify legacy PATA/IDE drive and controller documentation to select the correct UDMA mode.
  • Use this conversion to aid system configuration and confirm expected throughput ranges.
  • Consider system hardware and cable quality as they affect actual transfer speeds.
  • Understand that signaling differences mean conversions indicate theoretical rates, not exact performance.

Limitations

  • Conversion values represent theoretical maximum rates, which may vary in real usage.
  • Both units apply only to legacy PATA/IDE interfaces and are outdated compared to modern standards.
  • Timing and signaling differences mean converted values are for comparison, not direct equivalence.

Frequently Asked Questions

What is IDE (UDMA mode 3)?
IDE (UDMA mode 3) is an Ultra DMA transfer mode for Parallel ATA interfaces, offering about 44.4 MB/s maximum raw transfer rate with minimal CPU intervention.

Why convert IDE (UDMA mode 3) to IDE (UDMA mode 2)?
Converting helps compare data transfer speeds and configure legacy hardware for compatibility or troubleshooting by understanding different transfer rates and signaling profiles.

Are these conversions exact for real-world performance?
No, the conversions reflect theoretical maximum speeds and may differ from actual transfer rates due to hardware and configuration factors.

Key Terminology

IDE (UDMA mode 3)
A Parallel ATA Ultra DMA mode with about 44.4 MB/s theoretical max transfer rate, known as UDMA/44.
IDE (UDMA mode 2)
A Parallel ATA Ultra DMA mode (ATA/33) with a maximum theoretical transfer rate near 33.3 MB/s.
Ultra DMA (UDMA)
A data transfer protocol for Parallel ATA interfaces allowing efficient direct memory access for speed improvements.
