Limitations

Conversions are based on maximum theoretical transfer rates, not actual operating throughput
IDE (UDMA mode 2) and STS12 (signal) operate in fundamentally different hardware and protocol environments
STS12 data rates include framing and overhead that affect payload capacity compared to raw IDE transfers
Direct unit-to-unit conversion is mainly conceptual for analysis rather than practical data translation
