What does IDE (UDMA mode 1) represent?

IDE (UDMA mode 1) is an Ultra DMA transfer mode for Parallel ATA interfaces defining a theoretical maximum raw data transfer rate of about 25 MB/s, used in older PATA devices.

Why convert IDE (UDMA mode 1) rates to kilobit/second?

Converting to kilobit/second helps compare legacy PATA interface speeds with standardized networking units and aids in diagnostics and performance evaluation.

Are IDE (UDMA mode 1) transfer rates exact speeds?

No, these rates are theoretical maxima and actual performance depends on hardware, cables, and error correction.

Tips & Best Practices

Verify your hardware uses UDMA mode 1 when applying this conversion
Use this converter to assist with troubleshooting and benchmarking vintage drives
Compare converted speeds carefully, considering the theoretical nature of IDE mode speeds
Remember the kb/s unit uses the SI prefix of 1,000 bits, which may not perfectly match binary-based legacy measures
Use the converted values as guidance rather than exact sustained throughput

Limitations

The IDE (UDMA mode 1) transfer rate is a theoretical maximum, not guaranteed sustained speed
Actual throughput can be affected by hardware quality, cables, and error corrections
Kilobit/second (kb/s) uses the SI prefix meaning 1,000 bits per second, which may differ slightly from binary-based legacy units
