What Is This Tool?

This converter helps transform data transfer rates from IDE (PIO mode 4), a CPU-driven timing mode for older ATA/IDE devices, to IDE (UDMA mode 1), a faster Ultra DMA transfer mode used in vintage parallel ATA interfaces. It aids in comparison, configuration, and benchmarking of legacy storage hardware.

How to Use This Tool?

  • Enter the value in IDE (PIO mode 4) units you wish to convert
  • Select IDE (PIO mode 4) as the source unit
  • Choose IDE (UDMA mode 1) as the target unit
  • Click convert to get the corresponding transfer rate in IDE (UDMA mode 1)

Key Features

  • Converts data transfer rates from IDE (PIO mode 4) to IDE (UDMA mode 1)
  • Supports legacy ATA/IDE timing mode conversions
  • Useful for benchmarking and troubleshooting older storage devices
  • Browser-based and easy to use without additional software

Examples

  • 1 IDE (PIO mode 4) equals 0.664 IDE (UDMA mode 1)
  • 10 IDE (PIO mode 4) equals 6.64 IDE (UDMA mode 1)

Common Use Cases

  • Configuring or diagnosing BIOS and driver settings on vintage PCs
  • Benchmarking transfer speeds of legacy IDE storage devices
  • Troubleshooting compatibility issues in retro-computing and embedded systems

Tips & Best Practices

  • Use the converter to compare performance before upgrading legacy storage modes
  • Ensure motherboard and controller support the selected mode for compatibility
  • Apply conversions carefully since these modes reflect timing rather than actual data volume

Limitations

  • Both IDE (PIO mode 4) and IDE (UDMA mode 1) are legacy timing modes limited to older hardware
  • Theoretical throughput values do not necessarily reflect actual sustained speeds
  • Conversion relates to transfer timing modes, not absolute data sizes
  • Support depends on specific motherboard and controller compatibility

Frequently Asked Questions

What does IDE (PIO mode 4) mean?
IDE (PIO mode 4) is a CPU-controlled timing mode for ATA/IDE devices, representing an older method of data transfer with a maximum theoretical throughput around 16.7 MB/s.

How is IDE (UDMA mode 1) different from IDE (PIO mode 4)?
IDE (UDMA mode 1) is an Ultra DMA mode offering faster data transfer rates, approximately 25 MB/s, and includes error-checking and timing improvements over the CPU-driven PIO modes.

Can I use this conversion for modern storage devices?
No. These modes apply to legacy ATA/IDE hardware and timing configurations, mainly found in vintage or embedded systems.

Key Terminology

IDE (PIO mode 4)
A Programmed Input/Output timing mode where the CPU manages data transfers directly for ATA/IDE devices, with a max theoretical throughput of about 16.7 MB/s.
IDE (UDMA mode 1)
An Ultra DMA transfer mode in ATA/IDE devices with a maximum theoretical raw transfer rate of about 25 MB/s, used for timing and error-checking.
ATA/IDE
A set of standards for connecting storage devices to computers, often associated with parallel ATA interfaces and legacy devices.
