What Is This Tool?
This converter enables users to transform data transfer rates from STS1 (signal), a high-speed synchronous optical transport unit used in telecommunications, into IDE (PIO mode 1), a CPU-driven transfer mode for older PATA storage devices. It helps bridge understanding between modern network signals and legacy hardware data rates.
How to Use This Tool?

Tips & Best Practices
-
Use this tool to conceptually relate different data transfer technologies
-
Verify context and system overhead when interpreting conversion results due to differing platform characteristics
-
Apply conversions primarily for diagnostics, development, or benchmarking scenarios
-
Understand the inherent differences between network transport units and storage device modes
-
Confirm unit definitions and appropriate use cases before making technical decisions
Limitations
-
The conversion is conceptual and approximate due to different system contexts
-
STS1 is a high-speed optical network transport unit with SONET framing overhead
-
IDE (PIO mode 1) is a low-to-moderate throughput CPU-controlled storage transfer mode
-
Direct throughput comparisons between these units are platform-dependent
-
Conversion may not reflect actual performance in specific hardware or network scenarios
Frequently Asked Questions
-
What does STS1 (signal) represent?
-
STS1 (signal) is the basic SONET electrical/frame unit carrying a line rate of 51.84 megabits per second, corresponding to the OC-1 optical carrier and used for synchronous optical networking.
-
What is IDE (PIO mode 1)?
-
IDE (PIO mode 1) is a Programmed Input/Output transfer mode for PATA devices where the CPU controls each data transfer cycle, providing low-to-moderate throughput with higher CPU overhead.
-
Why convert between STS1 (signal) and IDE (PIO mode 1)?
-
Users convert these units to compare or relate data transfer rates between high-speed optical transport signals and legacy CPU-driven storage transfer modes, often for diagnostics or development.
