What does IDE (PIO mode 3) represent?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE storage devices with a theoretical maximum throughput of about 11.1 MB/s.

What is STS3 (payload)?

STS3 (payload) is the part of a SONET STS-3 (OC-3) frame that carries user data, representing the capacity available for client traffic excluding overhead.

Why convert from IDE (PIO mode 3) to STS3 (payload)?

Converting helps relate legacy IDE storage transfer rates to telecom payload capacities for performance evaluation and system integration.

Common Use Cases

Comparing throughput of older IDE storage devices to modern telecom payload capacities for performance evaluation.
Provisioning and capacity planning of carrier backbone links such as OC-3 circuits in telecommunications.
Measuring and billing leased-line services where payload bandwidth allocation matters.
Testing legacy desktop/laptop hard drives and CD/DVD devices used in BIOS or compatibility modes.
Integrating or designing embedded and industrial systems interfacing with older IDE devices without DMA.

Tips & Best Practices

Double-check the unit selections before converting to ensure accurate comparison.
Consider that IDE (PIO mode 3) throughput values are theoretical and CPU-dependent.
Remember STS3 (payload) excludes framing and overhead, representing only user data throughput.
Use this tool as a reference for planning rather than exact network or storage system performance.
Combine results with system-specific parameters for comprehensive capacity or performance evaluations.

Limitations

IDE (PIO mode 3) values are theoretical maxima and depend on CPU performance in real scenarios.
STS3 (payload) refers solely to the user data capacity and excludes overhead bytes in SONET frames.
The conversion does not factor in protocol overhead, error correction, or network conditions.
Results should be used cautiously in contexts requiring precise throughput or latency data.
