What Is This Tool?
This converter allows users to translate data transfer rates from STS3 (signal), a high-speed synchronous transport signal used in telecommunications, into IDE (PIO mode 2), a legacy ATA/IDE interface timing specification. It enables comparisons between modern network transmission speeds and older storage interface modes.
How to Use This Tool?
-
Enter the value in STS3 (signal) units you wish to convert
-
Select IDE (PIO mode 2) as the target unit
-
Start the conversion to get the equivalent IDE (PIO mode 2) value
-
Use the output to interpret or compare data transfer rates
-
Refer to examples for better understanding of conversions
Key Features
-

-
Provides conversion based on established rates for telecom and legacy interface units
-
Includes examples to help understand conversions between these units
-
Browser-based and easy to use for quick data comparisons
-
Useful for analysis of system performance and compatibility
Examples
-
1 STS3 (signal) equals approximately 2.3421686747 IDE (PIO mode 2)
-
5 STS3 (signal) converts to about 11.7108433735 IDE (PIO mode 2)
Common Use Cases
-
Interpreting telecom network speeds alongside legacy IDE drive timings
-
Configuring or diagnosing older PCs and firmware drive settings
-
Analyzing performance or compatibility issues where DMA falls back to PIO
-
Comparing modern synchronous optical signal rates with older storage interface methods
-
Supporting vintage computing and data recovery tasks involving IDE devices
Tips & Best Practices
-
Use this conversion to conceptually compare data transfer speeds rather than for direct practical throughput calculations
-
Verify the context when analyzing transfer modes, especially when working with legacy systems
-
Consider the technological differences between modern telecom signals and IDE interfaces
-
Refer to official device documentation when configuring BIOS or firmware IDE timings
-
Use multiple conversions and examples to ensure understanding of unit relationships
Limitations
-
The conversion is mainly conceptual due to fundamentally different technologies underlying the units
-
IDE PIO mode 2 has significantly lower throughput compared to STS3 signals
-
Direct interoperability between these units is limited
-
Conversion should not be used for precise performance measurement but for comparison or analysis
-
Differences in unit principles restrict practical application of this conversion
Frequently Asked Questions
