What Is This Tool?

This unit converter helps users translate data transfer rates between IDE (UDMA-66) and IDE (DMA mode 1), two legacy modes for IDE/ATA storage devices used in older computer systems.

How to Use This Tool?

  • Enter the value in IDE (UDMA-66) units.
  • Select IDE (DMA mode 1) as the target conversion unit.
  • View the converted result to assist in configuring or analyzing transfer modes.

Key Features

  • Converts data transfer units between IDE (UDMA-66) and IDE (DMA mode 1).
  • Supports legacy PATA (IDE) device transfer modes for better system configuration.
  • Browser-based and easy to use for quick mode comparison and tuning.

Examples

  • 1 IDE (UDMA-66) equals approximately 4.962406015 IDE (DMA mode 1).
  • 2 IDE (UDMA-66) converts to about 9.92481203 IDE (DMA mode 1).

Common Use Cases

  • Configuring BIOS transfer modes on legacy IDE hard drives and optical drives.
  • Verifying and comparing burst throughput capabilities of older PATA storage devices.
  • Troubleshooting and tuning performance on legacy IDE-based computer systems.

Tips & Best Practices

  • Ensure the devices and cables support the selected transfer mode for compatibility.
  • Use the conversion to align BIOS or driver settings with actual hardware capabilities.
  • Consider device age and system configuration when interpreting conversion results.

Limitations

  • Applicable only for legacy IDE/ATA hardware and related transfer modes.
  • Physical and timing constraints of devices affect real transfer speeds.
  • Conversion does not account for variations caused by cable quality or system age.

Frequently Asked Questions

What does IDE (UDMA-66) represent?
IDE (UDMA-66) is a Parallel ATA transfer mode known as Ultra DMA Mode 4 or ATA-66 that supports a maximum theoretical raw data rate of 66.7 MB/s using an 80-conductor cable.

Why convert to IDE (DMA mode 1)?
Converting to IDE (DMA mode 1) helps configure or troubleshoot legacy system settings for moderate-speed DMA data transfers that reduce CPU load.

Can this conversion be used with modern storage devices?
No, this conversion is intended only for legacy IDE/ATA devices and does not apply to modern storage interfaces.

Key Terminology

IDE (UDMA-66)
A legacy Parallel ATA mode (Ultra DMA Mode 4) supporting transfer rates up to 66.7 MB/s using an 80-conductor cable.
IDE (DMA mode 1)
A Direct Memory Access transfer mode for IDE devices that moves data with moderate speed and minimal CPU involvement.
PATA
Parallel ATA, an older interface standard for connecting storage devices in computers.
