What Is This Tool?
This tool allows you to convert data transfer speeds from IDE (UDMA mode 0), a high-speed PATA interface rate, to modem (110), a legacy low-speed modem transmission rate. It helps compare and analyze data rates from different technological eras.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 0) units you want to convert
-
Select the target unit as modem (110)
-
Click convert to see the equivalent data rate in modem (110)
Key Features
-
Converts data transfer rates between IDE (UDMA mode 0) and modem (110)
-
Browser-based and easy to use
-
Useful for diagnosing hardware performance or studying vintage communication speeds
Examples
-
1 IDE (UDMA mode 0) equals about 1,207,272.73 modem (110)
-
0.5 IDE (UDMA mode 0) equals about 603,636.36 modem (110)
Common Use Cases
-
Specifying or diagnosing throughput of legacy PATA/IDE drives
-
Troubleshooting DMA timing issues in BIOS or device drivers
-
Comparing legacy IDE interface speeds against modem bit rates for vintage computing research
-
Documenting old telemetry or serial communication data rates
Tips & Best Practices
-
Use this converter primarily for conceptual or historical analysis rather than real-world equivalence
-
Be aware that modem (110) rates can vary due to line quality, unlike IDE theoretical maxima
-
Consider the conversion as a means to compare vastly different data transfer technologies
Limitations
-
Conversion compares very different units (megabytes per second vs bits per second)
-
Primarily useful for historical or troubleshooting contexts, not for practical data transfer equivalency
-
Modem (110) speeds are nominal and affected by signal noise and line quality
Frequently Asked Questions
-
What does IDE (UDMA mode 0) represent?
-
IDE (UDMA mode 0) is an Ultra DMA transfer mode used for PATA/IDE devices with a nominal maximum raw data rate of approximately 16.7 megabytes per second.
-
What is modem (110) speed used for?
-
Modem (110) indicates a legacy data transmission speed around 110 bits per second, originally for early dial-up and teletype communication links.
-
Why convert between these two units?
-
Converting helps compare legacy high-speed PATA interface speeds with old low-speed modem bit rates, useful for troubleshooting, documentation, or vintage computing research.
Key Terminology
-
IDE (UDMA mode 0)
-
An Ultra DMA transfer mode for Parallel ATA devices with a nominal maximum raw data rate of about 16.7 megabytes per second.
-
Modem (110)
-
A legacy modem transmission speed of approximately 110 bits per second used for early dial-up and teletype communication links.
-
Data Transfer Rate
-
The amount of digital data moved from one place to another in a given time, expressed here in megabytes or bits per second.
