What Is This Tool?
This converter allows you to translate data transfer rates from STS1 (payload), a capacity measure in SONET networks, to IDE (PIO mode 4), an older ATA/IDE storage interface timing mode. It helps compare modern optical network speeds with legacy storage device throughputs.
How to Use This Tool?
-
Enter the value in STS1 (payload) you want to convert.
-
Select the target unit as IDE (PIO mode 4).
-
Click the convert button to get the result instantly.
-
Review the output to understand corresponding legacy storage interface speeds.
Key Features
-

-
Based on established conversion rates for accurate comparisons.
-
Supports telecommunications and legacy computing use cases.
-
Browser-based, easy-to-use interface.
-
Provides examples for quick reference.
Examples
-
1 STS1 (payload) converts to approximately 0.3727 IDE (PIO mode 4).
-
10 STS1 (payload) converts to approximately 3.7274 IDE (PIO mode 4).
Common Use Cases
-
Capacity planning and provisioning of OC-1/STS-1 circuits in SONET telecommunications.
-
Mapping tributary signals into optical transport payload for performance assessment.
-
Configuring and diagnosing legacy IDE/ATA drives and related BIOS or driver settings.
-
Benchmarking legacy storage performance for system upgrades.
-
Ensuring compatibility in industrial or retro-computing environments relying on ATA timing modes.
Tips & Best Practices
-
Always consider protocol overhead and hardware limitations when interpreting conversion results.
-
Use this tool as a comparative guide rather than an absolute performance measurement.
-
Verify system requirements when working with legacy IDE/ATA devices.
-
Combine network and storage data transfer insights for comprehensive system evaluations.
Limitations
-
Conversion compares a network payload rate in Mbps to a storage interface throughput in MB/s, which are different units and domains.
-
Results reflect theoretical maximums and may differ from real-world performance.
-
Interpret conversion outcomes with regard to protocol overhead and hardware constraints.
Frequently Asked Questions
