What does IDE (PIO mode 3) refer to in data transfer?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE devices, operating without DMA and offering a theoretical maximum speed of about 11.1 MB/s.

What is STS12 (signal) used for?

STS12 (signal) is a SONET synchronous transport signal with a line rate of 622.08 Mbit/s, commonly used in carrier networks and metro fiber links to transport framed digital payloads.

Can this tool give exact usable throughput between IDE and STS12?

No, the conversion provides a theoretical comparison and does not account for protocol overheads or real-world performance factors that affect usable throughput.

Tips & Best Practices

Remember that IDE (PIO mode 3) rates are in megabytes per second while STS12 is in megabits per second including overheads
Use this conversion to get a comparative perspective rather than exact usable throughput
Consider protocol overhead differences when interpreting converted values
Apply the tool for benchmarking in retrocomputing or embedded system scenarios
Cross-check conversion results with actual hardware or network performance for accuracy

Limitations

Conversion does not account for protocol overhead differences inherent in storage vs. optical signal standards
IDE (PIO mode 3) speeds exclude overhead, while STS12 line rates include framing and management bytes
Actual performance may vary significantly from theoretical maximum speeds based on hardware and network conditions
Converted values may not represent real usable throughput due to differing system architectures
Tool is intended for comparative analysis and planning, not precise throughput measurement
