-
Designing embedded and industrial systems requiring legacy IDE device integration
-
Evaluating and benchmarking performance in retrocomputing and storage device research
-
Comparing high-speed backbone signal capacity to legacy storage throughput speeds
Tips & Best Practices
-
Understand that STM-16 and IDE (PIO mode 3) represent different data contexts before comparing
-
Use conversion results primarily as a performance comparison guide, not exact equivalence
-
Consider CPU overhead and non-DMA limitation when interpreting IDE (PIO mode 3) throughput
-
Keep in mind STM-16 line rates refer to continuous digital signals, unlike disk I/O speeds
Limitations
-
Conversion involves comparing telecommunications signal rates to storage device transfer modes
-
IDE (PIO mode 3) is CPU-driven, so real throughput may be lower than theoretical maximum
-
STM-16 data rates represent continuous line rates unlike IDE device throughput bound by I/O operations
