Tips & Best Practices
-
Use this converter for benchmarking performance between telecom signals and legacy devices.
-
Verify compatibility of equipment when working with retro or embedded systems.
-
Remember the conversion provides a theoretical comparison, not exact real-world throughput.
Limitations
-
STM-4 and IDE (PIO mode 4) represent fundamentally different technologies and contexts.
-
Real throughput for IDE PIO mode 4 can be lower than theoretical due to CPU and hardware limits.
-
Conversion compares telecom line rates including overhead vs. storage data transfer timings.
Frequently Asked Questions
