Common Use Cases

Configuring or diagnosing legacy PATA hard drives in older systems.
Analyzing network bandwidth by translating legacy transfer rates to SONET payload levels.
Benchmarking data transfer scenarios in embedded or vintage systems using PIO modes.
Planning enterprise network capacity with reference to SONET/OC-3 circuits.

Tips & Best Practices

Use this tool for comparing transfer rates between legacy PATA devices and modern SONET transport networks.
Consider the higher CPU overhead in IDE (PIO mode 1) when analyzing throughput performance.
Remember that STS3c payload rates exclude SONET overhead which affects usable bandwidth.
Apply this conversion primarily for ideal condition estimations without accounting for protocol errors or extra overhead.

Limitations

IDE (PIO mode 1) mode has lower throughput and higher CPU usage compared to DMA or modern modes.
STS3c payload data excludes SONET framing overhead, so actual usable bandwidth is slightly less than the line rate.
This conversion assumes ideal conditions and does not include error rates or additional network protocol overhead.
