What is IDE (UDMA mode 1)?

IDE (UDMA mode 1) is an Ultra DMA transfer mode of the Parallel ATA interface that offers a theoretical maximum raw transfer rate of about 25 MB/s, mostly used in older PATA devices.

What does a gigabit per second measure?

A gigabit per second (Gb/s) quantifies data transfer rate equal to one billion bits transmitted each second, commonly used to specify digital communication bandwidth.

Why convert IDE (UDMA mode 1) to Gb/s?

Converting IDE (UDMA mode 1) to Gb/s helps translate legacy PATA transfer speeds into modern network bandwidth units for comparison, benchmarking, or integration with current data throughput standards.

Tips & Best Practices

Confirm the IDE (UDMA mode 1) rate input aligns with theoretical maximums for accuracy.
Be cautious in interpreting speeds as real-world throughput may be lower due to overhead.
Remember that IDE rates are byte-based, while gigabit/second rates are bit-based; interpret accordingly.
Use the conversion as a benchmark tool rather than an exact measured speed.
Consult hardware documentation to understand how this conversion applies to specific devices.

Limitations

IDE (UDMA mode 1) speeds represent theoretical maxima, not actual sustained rates.
Conversions do not account for overhead, error correction, or physical media effects.
Differences in unit bases (bytes vs. bits) require careful understanding to avoid misinterpretation.
Does not reflect real-world performance variability caused by hardware and protocol constraints.
