What Is This Tool?

This converter enables you to convert data transfer rates from IDE (UDMA-66) to IDE (UDMA mode 0), two legacy Parallel ATA transfer modes. It helps users compare performance and configure legacy PATA devices.

How to Use This Tool?

  • Enter the data transfer value in IDE (UDMA-66) mode
  • Select IDE (UDMA mode 0) as the target unit
  • Initiate the conversion to see the equivalent value
  • Use the results to assess performance or hardware compatibility

Key Features

  • Supports conversion between IDE (UDMA-66) and IDE (UDMA mode 0) data transfer rates
  • Provides theoretical maximum transfer rate conversions for legacy IDE interfaces
  • Simple interface to input values and get conversions instantly
  • Useful for diagnostics, benchmarking, and hardware configuration of PATA devices

Examples

  • Converting 2 IDE (UDMA-66) results in approximately 7.95 IDE (UDMA mode 0)
  • Converting 0.5 IDE (UDMA-66) results in around 1.99 IDE (UDMA mode 0)

Common Use Cases

  • Verifying maximum burst throughput of older PATA hard drives
  • Selecting or troubleshooting drive transfer modes in BIOS for compatibility
  • Diagnosing transfer speeds or errors on legacy IDE systems
  • Comparing legacy PATA limits when upgrading to newer interfaces like SATA or USB

Tips & Best Practices

  • Always verify device and controller support for the target transfer mode
  • Use the conversion to assist in troubleshooting or benchmarking legacy hardware
  • Recognize that actual speeds may be affected by cable quality and device conditions
  • Apply conversions mainly for legacy systems, as modern drives use newer interfaces

Limitations

  • Conversion is based on theoretical maximum data transfer rates only
  • Does not account for real-world overhead or device-specific performance differences
  • Applies solely to legacy PATA/IDE interfaces, not modern standards like SATA or NVMe

Frequently Asked Questions

What does IDE (UDMA-66) mean?
IDE (UDMA-66), also known as Ultra DMA Mode 4 or ATA‑66, is a Parallel ATA transfer mode defining a maximum raw data rate of 66.7 megabytes per second, using an 80-conductor PATA cable.

Why convert IDE (UDMA-66) to IDE (UDMA mode 0)?
Conversion helps understand and compare transfer speeds between legacy PATA modes, which is useful for diagnosing performance or configuring older hardware.

Can this converter be used for modern SATA drives?
No, this tool is designed exclusively for legacy PATA/IDE interfaces and does not apply to SATA or NVMe devices.

Key Terminology

IDE (UDMA-66)
A Parallel ATA transfer mode with a max theoretical data rate of 66.7 MB/s, requiring an 80-conductor PATA cable.
IDE (UDMA mode 0)
Ultra DMA transfer mode 0 for PATA devices, defining interface timing with a max nominal data rate of about 16.7 MB/s.
PATA (Parallel ATA)
Legacy interface standard for connecting storage devices, preceded SATA and NVMe technologies.
