What Is This Tool?
This converter allows you to translate data transfer rates between STS3c (payload), used in optical transport networks, and IDE (UDMA mode 0), a transfer mode for legacy Parallel ATA devices. It helps estimate equivalent throughput and supports performance evaluation across different technologies.
How to Use This Tool?
-
Enter the value in STS3c (payload) units you want to convert
-
Select IDE (UDMA mode 0) as the target unit
-
Click convert to get the equivalent transfer rate
-
Use the results to analyze or compare data throughput between interfaces
Key Features
-
Converts data rates from STS3c (payload) to IDE (UDMA mode 0)
-
Includes practical examples for quick reference
-
Supports telecommunications and IT system use cases
-
Browser-based and user-friendly interface
-
Useful for comparing high-speed optical and legacy PATA data transfers
Examples
-
1 STS3c (payload) equals approximately 1.132 IDE (UDMA mode 0)
-
5 STS3c (payload) equals approximately 5.66 IDE (UDMA mode 0)
Common Use Cases
-
Estimating data throughput between optical backbone links (OC-3) and legacy drives
-
Troubleshooting and diagnosing PATA/IDE device speed issues
-
Supporting technology migration analysis from PATA to SATA or USB interfaces
-
Comparing performance of SONET transport channels with legacy DMA modes
Tips & Best Practices
-
Consider protocol overhead which slightly reduces usable STS3c payload rates
-
Use conversions to aid performance comparisons rather than exact measurements
-
Validate results with device specifications and system configurations
-
Apply conversions primarily for estimation and troubleshooting purposes
Limitations
-
STS3c payload rates are slightly less due to SONET framing overhead
-
IDE (UDMA mode 0) transfer rates indicate nominal maximum speeds only
-
Differences in protocol and transfer methods make conversions approximate
-
Device conditions and system settings may affect actual throughput
Frequently Asked Questions
-
What does STS3c (payload) represent?
-
STS3c (payload) is the concatenated Synchronous Transport Signal level-3 container in SONET, providing a contiguous transport channel with a gross line rate of 155.52 Mbps for optical networks.
-
What is IDE (UDMA mode 0)?
-
IDE (UDMA mode 0) is an Ultra DMA transfer mode for Parallel ATA devices, defining timing and a nominal maximum data transfer rate of about 16.7 MB/s.
-
Why convert between STS3c (payload) and IDE (UDMA mode 0)?
-
Converting between these units helps estimate equivalent throughput between high-speed optical channels and legacy PATA devices, supporting troubleshooting and performance comparisons.
