What does IDE (UDMA-33) represent?

IDE (UDMA-33) is a legacy PATA data transfer mode that moves data using direct memory access at a theoretical maximum burst rate of 33.3 MB/s.

Why convert IDE (UDMA-33) speeds to gigabyte/second SI?

Converting to gigabyte/second (SI) provides a modern, standardized unit to compare legacy system speeds with current storage and network devices.

Can I use this conversion for modern storage devices?

No, this conversion is specific to legacy IDE (UDMA-33) technology and less applicable for recent high-speed storage standards.

What Is This Tool?

This converter allows you to translate data transfer speeds from IDE (UDMA-33), a legacy Parallel ATA standard, into gigabytes per second using the SI decimal system. It aids in expressing older PATA technology transfer rates in modern, standardized units.

How to Use This Tool?

Enter the value in IDE (UDMA-33) units that you want to convert.
Select IDE (UDMA-33) as the source unit and gigabyte/second (SI def.) as the target unit.
Click the convert button to get the equivalent data transfer rate in gigabytes per second.
Review the result, which reflects the data transfer in modern SI units.

Key Features

Converts IDE (UDMA-33) data transfer rates to gigabytes per second (SI definition).
Supports legacy PATA data-transfer mode commonly found in older hard and optical drives.
Uses official conversion rate consistent with theoretical maximum IDE (UDMA-33) burst speed.
Facilitates easy benchmarking and comparison between legacy and modern storage devices.

Examples

1 IDE (UDMA-33) equals 0.033 gigabyte per second (SI def.).
5 IDE (UDMA-33) converts to 0.165 gigabyte per second (SI def.).

Common Use Cases

Benchmarking throughput of legacy PATA hard drives and optical drives.
Configuring or troubleshooting BIOS or controller transfer modes on older computer systems.
Comparing legacy PATA device speeds when upgrading or replacing hardware components.
Expressing throughput in modern units for easier understanding and documentation.

Tips & Best Practices

Ensure you select the correct source and target units before converting.
Use this converter primarily for legacy hardware analyses and documentation purposes.
Cross-check results when integrating older devices into modern infrastructure to avoid confusion.
Remember that actual speed may vary due to hardware and cable quality.

Limitations

IDE (UDMA-33) speeds represent theoretical maximums and real-world speeds can be lower.
The gigabyte/second unit uses the SI decimal definition, differing from binary gigabyte definitions used elsewhere and possibly causing confusion.
This tool applies to outdated technology, limiting relevance mostly to legacy system support and benchmarking.
