What Is This Tool?
This converter allows users to translate data transfer speeds from the Modem (2400) standard, representing early dial-up modem rates, to the Ultra DMA mode 1 transfer rate used by legacy IDE (PATA) devices. It is helpful for understanding and comparing old communication and storage throughput.
How to Use This Tool?
-
Enter the numeric value in Modem (2400) units you want to convert
-
Select Modem (2400) as the source unit and IDE (UDMA mode 1) as the target unit
-
Click the convert button to see the equivalent transfer rate in IDE (UDMA mode 1)
-
Review the output and apply it to retro-computing or data benchmarking tasks as needed

-
1000 Modem (2400) converts to 0.012 IDE (UDMA mode 1)
Common Use Cases
-
Comparing extremely low dial-up modem speeds with much higher IDE transfer modes in retro-computing
-
Benchmarking and diagnosing legacy hardware transfer settings on vintage PCs
-
Testing compatibility and performance of older modems and PATA drives
-
Educational purposes and historical data rate conversions
-
Troubleshooting controller or cable issues related to IDE UDMA modes
Tips & Best Practices
-
Verify unit selections carefully to ensure accurate conversion context
-
Use conversions primarily for historical reference or legacy system benchmarking
-
Cross-check conversions with expected theoretical rates for troubleshooting
-
Consider hardware and system limitations affecting actual data speeds
-
Refer to documentation on vintage modems and IDE modes for detailed understanding
Limitations
-
Modem (2400) rate is a descriptive gross bit rate, not an official SI unit
-
IDE (UDMA mode 1) values represent theoretical maximum speeds, not actual performance
-
Conversions are approximate and intended for educational or retro-computing uses
-
Not suitable for modern data transfer rate measurements or applications
-
Actual transfer rates depend heavily on specific hardware and configurations
Frequently Asked Questions
-
What does Modem (2400) represent?
-
Modem (2400) denotes a data transfer rate of 2400 bits per second, typical of early dial-up modem standards like ITU-T V.22bis.
-
What is IDE (UDMA mode 1)?
-
IDE (UDMA mode 1) is a transfer mode in the Parallel ATA interface providing a theoretical maximum raw transfer rate of about 25 MB/s on older PATA devices.
-
Why convert between Modem (2400) and IDE (UDMA mode 1)?
-
Users convert between these units to compare the low data rates of vintage modems with the higher throughput of legacy IDE storage modes, useful in retro-computing and benchmarking.
Key Terminology
-
Modem (2400)
-
A classification representing modem data-transfer speeds of 2400 bits per second common in early dial-up connections.
-
IDE (UDMA mode 1)
-
An Ultra DMA transfer mode for older Parallel ATA devices with a maximum raw transfer rate near 25 MB/s.
-
Data Transfer Rate
-
The speed at which data is transmitted from one device to another, measured in bits per second or bytes per second.
