What does modem (28.8k) represent?

Modem (28.8k) is an informal term for a data transfer rate of approximately 28,800 bits per second over analog telephone lines typical of 28.8k dial-up modems.

What is IDE (UDMA mode 2)?

IDE (UDMA mode 2), also known as ATA/33, is a transfer mode for PATA interfaces with a maximum theoretical transfer rate of about 33.3 megabytes per second.

Can I directly interchange data rates between modem (28.8k) and IDE (UDMA mode 2)?

No. These units measure fundamentally different technologies; the conversion is for conceptual comparison rather than exact practical equivalence.

What Is This Tool?

This tool allows you to convert data transfer rates from modem (28.8k), an informal measure of 28.8 kilobits per second on dial-up lines, to IDE (UDMA mode 2), an ultra DMA transfer mode used by legacy PATA interfaces with a theoretical maximum around 33.3 megabytes per second.

How to Use This Tool?

Enter the value in modem (28.8k) units you want to convert.
Select modem (28.8k) as the source unit and IDE (UDMA mode 2) as the target unit.
Click the convert button to see the equivalent transfer rate in IDE (UDMA mode 2).
Analyze the converted results to compare legacy modem performance against PATA IDE transfer speeds.

Key Features

Converts between two legacy data transfer rate units relevant to retro computing and legacy technology.
Supports comparison between modem dial-up rates and PATA IDE disk interface speeds.
Displays conversion based on a precise conversion factor derived from unit definitions.
Browser-based and simple to use without needing technical knowledge of transfer protocols.

Examples

10 modem (28.8k) converts to approximately 0.001090909 IDE (UDMA mode 2).
100 modem (28.8k) converts to approximately 0.01090909 IDE (UDMA mode 2).

Common Use Cases

Estimating download times and comparing dial-up modem speeds for retro computing applications.
Configuring or interpreting legacy PATA IDE controller settings and benchmarking older drives.
Troubleshooting and diagnosing performance or compatibility issues in legacy systems involving modems and IDE drives.
Understanding relative throughput speeds in archival technology and data recovery projects.

Tips & Best Practices

Use the conversion to get conceptual comparisons rather than expecting direct practical interchange.
Remember the fundamental difference that modem rates are in bits per second over analog lines, while IDE UDMA speed is in megabytes per second on synchronous interfaces.
Apply this tool mainly for legacy system evaluation, retro computing studies, or archival technology contexts.

Limitations

The conversion compares fundamentally different technologies with different units and measurement contexts.
Real-world speeds may vary significantly due to factors like protocol overhead, signal quality, and hardware limitations.
This conversion provides mostly a reference perspective rather than a precise practical equivalence.
