What Is This Tool?
This converter transforms data transfer measurements from STS3c (payload), a high-bandwidth optical transport signal, into IDE (DMA mode 2), a legacy parallel ATA data transfer mode. It helps compare and translate transfer rates between different technologies.
How to Use This Tool?
-
Input the value representing STS3c (payload) data rate.
-
Select STS3c (payload) as the source unit and IDE (DMA mode 2) as the target unit.
-
Execute the conversion to obtain the equivalent IDE (DMA mode 2) value.
Key Features
-
Converts data transfer units from STS3c (payload) to IDE (DMA mode 2).
-
Applies a precise conversion factor based on standardized rates.
-
Supports users working with telecommunications and legacy hardware.
Examples
-
1 STS3c (payload) converts to 1.1320481928 IDE (DMA mode 2).
-
5 STS3c (payload) converts to 5.660240964 IDE (DMA mode 2).
Common Use Cases
-
Comparing data throughput between optical transport networks and legacy storage devices.
-
Benchmarking and diagnostics in telecommunications backbone and enterprise leased-line setups.
-
Configuring and troubleshooting legacy PATA/IDE hardware and firmware environments.
Tips & Best Practices
-
Ensure you understand the differences and limitations of the underlying technologies before interpreting conversion results.
-
Use this conversion primarily for benchmarking and comparison purposes in contexts involving both optical and legacy interfaces.
-
Cross-check results against actual device specifications and network protocols due to protocol overhead differences.
Limitations
-
STS3c (payload) reflects a gross line rate that includes SONET framing overhead, so actual payload bandwidth is slightly lower.
-
IDE (DMA mode 2) is a legacy mode limited by older hardware and does not represent modern transfer speeds.
-
Conversions may not exactly represent real-world performance because of differences in protocols and technology types.
Frequently Asked Questions
-
What does STS3c (payload) represent?
-
STS-3c (payload) is the concatenated Synchronous Transport Signal level-3 payload in SONET providing a contiguous transport channel with a line rate of 155.52 Mbps.
-
What is IDE (DMA mode 2)?
-
IDE (DMA mode 2) is a Parallel ATA data transfer mode that allows devices to move data efficiently with less CPU involvement in legacy PATA/IDE hardware.
-
Why convert between STS3c (payload) and IDE (DMA mode 2)?
-
Conversion helps compare data transfer speeds across optical transport networks and legacy storage interfaces for performance benchmarking and diagnostics.
