Tips & Best Practices

Use this converter for rough equivalence to aid in understanding rather than precise engineering calculations
Remember that STS24 includes protocol overhead which affects usable payload versus raw data rates
Consider additional factors like protocol inefficiencies and real-world throughput variations outside of conversion results
Verify compatibility with both device and controller when dealing with legacy IDE configurations

Limitations

Conversion rates reflect theoretical values and do not represent actual throughput under all conditions
IDE (UDMA-66) values are raw megabytes per second bursts; STS24 rates include line overhead reducing payload
Differences in encoding schemes and protocol overhead are not accounted for in this converter
Best used for conceptual comparisons rather than detailed network engineering
