Tips & Best Practices

Ensure the input values represent theoretical or measured throughput for accurate conversions
Remember that real-world throughput may vary due to hardware and protocol overheads
Use the conversion results as a relative comparison rather than absolute performance metrics

Limitations

IDE (PIO mode 3) throughput is CPU-driven and theoretical; actual rates can differ due to system overhead
STS1 (signal) data rate includes SONET overhead, so useful payload is less than the raw line rate
This converter focuses on raw data rates and does not consider protocol or transmission inefficiencies
