Verify that conversions are used in scenarios where theoretical transfer rates suffice
Be aware of the different domains of the units—PATA interface versus optical networking
Use multiple examples to confirm accuracy of conversion outcomes

Limitations

Conversion is based solely on theoretical maximum transfer rates
Does not consider protocol overhead or real-world throughput drops
IDE (UDMA mode 1) is a legacy mode with limited modern practical use
STS3c signals operate in optical networking, so direct application is often for benchmarking or integration contexts
The conversion factor reflects raw rate equivalence, not detailed performance or protocol specifics
