What is IDE (UDMA mode 1)?

IDE (UDMA mode 1) is a transfer mode of the Parallel ATA interface, offering a maximum raw data transfer rate of about 25 MB/s, used primarily in older PATA devices.

What does modem (300) represent?

Modem (300) refers to a data transfer speed of 300 bits per second, typical of early analog dial-up modem standards.

Why convert IDE (UDMA mode 1) to modem (300)?

This conversion helps compare modern or legacy IDE data transfer rates with early modem speeds, useful in vintage computing diagnostics and historical analysis.

Tips & Best Practices

Remember that IDE (UDMA mode 1) rates are in bytes per second, while modem (300) is in bits per second.
Use this converter to understand relative throughputs rather than exact real-world performance.
Consider hardware conditions and protocol differences when interpreting conversions.

Limitations

Conversion is theoretical, reflecting maximum transfer speeds rather than actual throughput.
Differences in data unit measurements (bytes vs bits per second) require careful interpretation.
Protocol overhead and error correction differences mean direct equivalence may not represent real performance.
