What Is This Tool?
This converter transforms data transfer rates from STM-1 (signal), a high-speed telecom transmission unit, to IDE (PIO mode 3), a legacy storage device transfer mode. It enables users to compare different data throughput standards relevant to telecommunications and older computing interfaces.
How to Use This Tool?
-
Enter the value in STM-1 (signal) units you wish to convert
-
Select STM-1 (signal) as the input unit and IDE (PIO mode 3) as the output unit

Examples
-
1 STM-1 (signal) converts to approximately 1.75 IDE (PIO mode 3)
-
5 STM-1 (signal) equals about 8.76 IDE (PIO mode 3)
-
Use these conversions to benchmark transfer rates between SDH telecom links and IDE storage modes
Common Use Cases
-
Provisioning backbone fiber links in telecom networks with STM-1 links
-
Supporting embedded or industrial systems interfacing with older IDE devices
-
Performing compatibility tests and retrocomputing comparisons of legacy storage methods
-
Interfacing or transitioning between SDH and legacy hardware environments
-
Benchmarking performance between telecom transmission units and storage transfer modes
Tips & Best Practices
-
Remember that actual transfer speeds may vary due to hardware and protocol factors
-
Use the converter to compare theoretical throughput rather than precise real-world speeds
-
Combine conversion results with hardware specifications for comprehensive system design
-
Utilize this tool for understanding legacy system performance in modern contexts
-
Verify converted values when planning cross-interface communication or testing
Limitations
-
Conversion compares bit rates with throughput rates influenced by CPU and interface constraints
-
IDE (PIO mode 3) is a legacy interface with throughput limits that differ from modern standards
-
Actual data transfer speeds may differ due to overheads and protocol implementations
-
The tool provides an approximate equivalence, not exact real-world performance measurements
