Tips & Best Practices

Verify that the controller and cable support the IDE (UDMA-33) mode for accurate source data.
Use this conversion as a theoretical guide rather than exact real-world throughput measurements.
Consider protocol overhead and encoding differences when comparing results between units.
Apply conversions primarily for network planning or legacy system integration purposes.

Limitations

Conversion is based on theoretical maximum transfer rates, not actual sustained throughput.
Does not address protocol overhead or encoding differences between PATA and SONET/SDH standards.
Results are not indicative of real-time or average data transfer speeds in practice.
