What Is This Tool?
This online converter allows you to translate data transfer rates from IDE (UDMA-66) units, representing burst throughput of legacy PATA devices, into modem (110) units, which denote the bit rate of early modem communication speeds. It is ideal for users working with vintage computing and historical data communication systems.
How to Use This Tool?
-
Enter the value in IDE (UDMA-66) units that you want to convert
-
Select the target unit as modem (110) from the options
-
Click the convert button to see the equivalent modem (110) speed
-
Review the results and apply them for benchmarking or documentation
Key Features
-
Converts between IDE (UDMA-66) and modem (110) data transfer units
-
Supports understanding of legacy PATA drive transfer modes and early modem speeds
-
Browser-based and easy to use without any software installation
-
Ideal for historical and educational data rate comparisons
-
Provides clear examples to illustrate conversions
Examples
-
Converting 1 IDE (UDMA-66) yields 4,800,000 modem (110)
-
Half an IDE (UDMA-66) unit equals 2,400,000 modem (110)
Common Use Cases
-
Comparing burst throughput of legacy PATA storage with early modem communication rates
-
Benchmarking data transfer rates between parallel ATA drives and vintage dial-up modems
-
Emulating or documenting historic data link performances in vintage computing
-
Supporting technical research and maintenance for obsolete hardware and telecommunication systems
Tips & Best Practices
-
Remember that IDE (UDMA-66) rates represent burst throughput, whereas modem (110) rates describe sustained bit rates
-
Use conversions primarily for historical or educational insights rather than real-world throughput comparisons
-
Consider protocol overheads and data encoding differences when interpreting results
-
Keep the legacy context in mind for accurate benchmarking and documentation
Limitations
-
IDE (UDMA-66) transfer rates indicate theoretical maximum bursts in megabytes per second, while modem (110) rates are low-speed serial transmission bit rates
-
Direct performance comparisons may be inaccurate due to differing communication protocols and encoding methods
-
The extremely low speeds of modem (110) make this converter mainly useful for historical or educational purposes
-
Not intended for modern practical data transfer evaluations
Frequently Asked Questions
-
What is IDE (UDMA-66)?
-
IDE (UDMA-66), also known as Ultra DMA Mode 4 or ATA-66, is a Parallel ATA transfer mode specifying a maximum raw data rate of 66.7 megabytes per second used in legacy PATA storage devices.
-
What does modem (110) represent?
-
Modem (110) refers to a legacy modem transmission speed of approximately 110 bits per second, used in early dial-up and teletype communication systems.
-
Why convert from IDE (UDMA-66) to modem (110)?
-
Users convert these units to compare or understand data transfer speeds between modern legacy storage devices and early dial-up modems, useful in benchmarking and vintage system analysis.
