What Is This Tool?

This converter tool helps transform data transfer values between IDE (UDMA-66) and IDE (UDMA mode 3), two legacy Parallel ATA transfer modes used for older PATA/IDE hard drives and optical drives. It supports configuring BIOS transfer modes and interpreting system benchmarks.

How to Use This Tool?

  • Enter the value in IDE (UDMA-66) units you want to convert
  • Select IDE (UDMA-66) as the source unit and IDE (UDMA mode 3) as the target unit
  • Click the convert button to see the equivalent transfer rate in IDE (UDMA mode 3)
  • Use the results to configure BIOS or evaluate legacy drive compatibility

Key Features

  • Converts data transfer rates between IDE (UDMA-66) and IDE (UDMA mode 3)
  • Displays theoretical maximum raw transfer conversions explicitly
  • Supports legacy PATA/IDE storage device transfer mode configurations
  • Browser-based and easy to use with no installation needed
  • Facilitates troubleshooting and diagnostics for older hardware systems

Examples

  • 1 IDE (UDMA-66) equals 1.32 IDE (UDMA mode 3)
  • 5 IDE (UDMA-66) equals 6.6 IDE (UDMA mode 3)

Common Use Cases

  • Comparing transfer rates between older PATA/IDE hard drives and optical drives
  • Configuring transfer modes in BIOS or drive firmware on legacy PCs
  • Troubleshooting and refurbishing vintage computer systems
  • Interpreting benchmark results for legacy IDE storage devices

Tips & Best Practices

  • Verify device and controller support before selecting transfer modes
  • Use quality 80-conductor PATA cables to ensure optimal transfer capabilities
  • Refer to system documentation when configuring BIOS transfer modes
  • Consider that actual sustained speeds may vary from theoretical rates

Limitations

  • Conversion values represent theoretical maximum raw data rates only
  • Actual transfer speeds may differ due to hardware and system factors
  • Applicable mainly to legacy PATA/IDE hardware, now largely obsolete
  • Does not guarantee exact compatibility or performance improvements

Frequently Asked Questions

What does IDE (UDMA-66) mean?
IDE (UDMA-66) is a Parallel ATA transfer mode also known as Ultra DMA Mode 4 or ATA-66, providing a maximum theoretical data rate of 66.7 MB/s and requiring specific cable and device support.

How is IDE (UDMA mode 3) different?
IDE (UDMA mode 3) is an Ultra DMA mode with a lower maximum theoretical transfer rate of about 44.4 MB/s, used for configuring and benchmarking legacy PATA/IDE drives.

Why would I convert between these two modes?
Users convert to compare, configure, and troubleshoot transfer rates for legacy PATA/IDE storage devices, especially during BIOS setup or system diagnostics.

Key Terminology

IDE (UDMA-66)
A Parallel ATA transfer mode with a maximum theoretical data rate of 66.7 MB/s, also known as Ultra DMA Mode 4 or ATA-66, requiring 80-conductor cables and controller support.
IDE (UDMA mode 3)
An Ultra DMA transfer mode with a theoretical maximum raw transfer rate around 44.4 MB/s, used for configuring legacy PATA/IDE drives and reducing CPU involvement.
PATA
Parallel ATA, an interface standard for connecting storage devices like hard drives and optical drives in older computers.
