What Is This Tool?

This converter allows you to transform data transfer values from IDE (DMA mode 2), a high-throughput DMA transfer mode in legacy PATA/IDE devices, to IDE (PIO mode 3), a CPU-driven programmed I/O transfer mode. It is useful for comparing and diagnosing transfer modes in older storage hardware.

How to Use This Tool?

  • Enter the value in IDE (DMA mode 2) units you wish to convert
  • Select IDE (PIO mode 3) as the target unit
  • Click the convert button to see the equivalent value
  • Use the result to analyze and compare data transfer performance
  • Repeat as needed for different values or settings

Key Features

  • Converts data transfer units between IDE (DMA mode 2) and IDE (PIO mode 3)
  • Supports legacy PATA/IDE interface standards
  • Facilitates performance comparison between DMA and PIO modes
  • Browser-based and easy to use
  • Helps in firmware, driver configuration, and troubleshooting

Examples

  • 1 IDE (DMA mode 2) equals approximately 1.50 IDE (PIO mode 3)
  • 2 IDE (DMA mode 2) equal approximately 2.99 IDE (PIO mode 3)

Common Use Cases

  • Configuring or diagnosing legacy PATA/IDE hard drives and optical drives
  • Firmware or BIOS mode negotiation for older IDE devices
  • Benchmarking and troubleshooting storage interfaces on legacy systems
  • Compatibility testing and retrocomputing applications
  • Embedded or industrial systems maintenance with older hardware

Tips & Best Practices

  • Understand which transfer mode your device is using before converting
  • Use conversion results to balance CPU overhead and transfer speed
  • Consider conversion values as part of broader performance diagnostics
  • Confirm device compatibility with IDE (DMA mode 2) or IDE (PIO mode 3)
  • Apply conversions mainly to legacy PATA/IDE interfaces, not modern devices

Limitations

  • Applicable only to legacy Parallel ATA/IDE standards, not SATA or NVMe
  • Theoretical throughput values may vary due to hardware and system factors
  • Conversion does not account for latency or error rates in transfers
  • Does not reflect all aspects of device or system performance
  • Use results as a general guide, not precise measurement

Frequently Asked Questions

What does IDE (DMA mode 2) mean?
IDE (DMA mode 2) is a data transfer mode for legacy PATA/IDE devices that moves data directly with minimal CPU use, improving throughput compared to PIO modes.

What is IDE (PIO mode 3)?
IDE (PIO mode 3) is a CPU-driven programmed I/O mode for Parallel ATA/IDE devices with a maximum transfer rate of about 11.1 MB/s.

Why would I convert between these modes?
Converting between these modes helps compare performance characteristics, diagnose transfer configurations, and optimize legacy device settings.

Key Terminology

IDE (DMA mode 2)
A legacy Parallel ATA data transfer mode that uses Direct Memory Access to reduce CPU usage and increase throughput.
IDE (PIO mode 3)
A programmed I/O transfer mode where the CPU manages data transfer for Parallel ATA devices, offering lower throughput.
PATA/IDE
Parallel ATA or Integrated Drive Electronics, an older interface standard for connecting storage devices.
