What Is This Tool?
This converter allows you to translate data transfer values from OC3, a SONET optical transmission rate, into IDE (DMA mode 2) units, a parallel ATA data-transfer mode. It helps users compare high-speed network interfaces with legacy storage transfer technologies.
How to Use This Tool?
-
Enter the value you want to convert in the OC3 field
-
Select the target unit as IDE (DMA mode 2)
-
Click the convert button to obtain the conversion result
-
Use the output to analyze or compare data transfer rates across technologies
Key Features
-
Converts data transfer rates between OC3 and IDE (DMA mode 2) units
-
Based on established conversion rates and clear formulas
-
Suitable for telecommunications and legacy hardware contexts
-
Browser-based and easy to use with instant results
-
Supports users in configuring and troubleshooting systems involving both technologies
Examples
-
1 OC3 equals 1.1710843373 IDE (DMA mode 2)
-
5 OC3 converts to 5.8554216865 IDE (DMA mode 2)
Common Use Cases
-
Comparing high-speed optical network transfer rates with legacy storage transfer modes
-
Configuring or diagnosing legacy PATA/IDE devices that use DMA mode 2
-
Troubleshooting systems involving both modern network backbone and older storage hardware
-
Network and system administrators balancing throughput and hardware diagnostics
-
Evaluating leased WAN circuits and backbone link capacities alongside storage transfer performance
Tips & Best Practices
-
Ensure input values represent actual measured transfer rates for more meaningful comparisons
-
Use the conversion to guide configuration or debugging of systems bridging network and storage technologies
-
Be aware that these units relate to different technologies—treat the conversion mostly as conceptual
-
Combine this tool with other diagnostics for comprehensive system assessment
-
Remember that IDE DMA mode 2 is a legacy standard, so limit use in modern system contexts
Limitations
-
OC3 and IDE (DMA mode 2) represent fundamentally different data transfer technologies
-
Conversion is conceptual and assumes ideal conditions without real-world overhead or protocol effects
-
IDE DMA mode 2 is a legacy interface, so relevance is reduced in current hardware environments
Frequently Asked Questions
-
What does OC3 represent in data transfer?
-
OC3 is an optical transmission rate used in SONET networks operating at 155.52 megabits per second, mainly for long-distance fiber optic backbone transport.
-
What is IDE (DMA mode 2)?
-
IDE (DMA mode 2) is a parallel ATA data-transfer mode allowing direct memory access for data movement with higher throughput and less CPU overhead compared to PIO modes, typical in legacy PATA/IDE devices.
-
Can I use this conversion for modern system performance assessment?
-
Due to the legacy nature of IDE DMA mode 2 and the differing technologies these units represent, this conversion is more conceptual and less applicable for modern hardware performance evaluations.
Key Terminology
-
OC3
-
A SONET optical transmission rate of 155.52 megabits per second used in backbone fiber optic networks and carrying aggregated lower-rate channels.
-
IDE (DMA mode 2)
-
A Parallel ATA data-transfer mode enabling direct memory access with minimal CPU intervention for legacy PATA/IDE devices.
-
Data Transfer Rate
-
The speed at which data is moved from one location to another, measured in units such as megabits per second or transfer modes.
