-
Provides a clear conversion formula for reference
-
Browser-based and easy to use without requiring installation
-
Useful for engineers, technicians, and analysts working with varied data transfer technologies
Examples
-
1 IDE (UDMA mode 3) equals approximately 2.572 STS3 (signal)
-
2 IDE (UDMA mode 3) converts to about 5.144 STS3 (signal)
Common Use Cases
-
Comparing throughput of legacy PATA/IDE drives with SONET transmission rates
-
Configuring or interpreting drive modes in legacy computer systems
-
Analyzing telecom backbone links with mixed technology components
-
Troubleshooting or refurbishing older storage and network equipment

Tips & Best Practices
-
Use this tool primarily for comparative and analytical purposes rather than practical data transfer
-
Consider hardware and protocol overheads that influence real-world throughput
-
Apply conversion when documenting or interpreting legacy and modern data transport rates side-by-side
-
Keep in mind the different nature of the units involved: byte-based transfers vs. synchronous optical bit rates
Limitations
-
Conversion is theoretical due to differing technologies and measurement units
-
Real throughput can vary because of hardware, protocols, and network conditions
-
Not suitable for direct interoperability or precise transfer calculations
-
Best used for historical data, comparative analysis, and understanding mixed-technology contexts
Frequently Asked Questions
-
What does IDE (UDMA mode 3) measure?
-
IDE (UDMA mode 3) is a legacy Parallel ATA Ultra DMA mode providing a theoretical maximum raw transfer rate of around 44.4 MB/s with minimal CPU intervention.
