Tips & Best Practices

Use this conversion primarily for conceptual comparisons rather than precise data transfer calculations.
Consider device and system specifics impacting IDE (DMA mode 2) rates when interpreting conversions.
Remember that STM-16 signals represent continuous line rates, not instantaneous device transfer bursts.
Apply conversion results as a guide in legacy IT system benchmarking or telecom network planning contexts.

Limitations

IDE (DMA mode 2) speeds vary by device and system and are much slower than STM-16 signals, so comparison is mostly conceptual.
Direct equivalence does not account for differences in protocols or overhead affecting real data transfers.
STM-16 figures assume continuous capacity; IDE transfers depend on activity patterns and bus efficiency.
This conversion is not suitable for exact throughput matching or performance prediction.
