What Is This Tool?
This converter transforms data transfer values from IDE (DMA mode 2), a legacy Parallel ATA interface mode, into STM-64 (signal), a modern high-speed synchronous transport module used in telecommunications networks.
How to Use This Tool?
-
Enter the numerical value in IDE (DMA mode 2) units.
-
Select STM-64 (signal) as the target unit.
-
Click convert to get the equivalent STM-64 (signal) rate.
Key Features
-
Converts data transfer rates from IDE (DMA mode 2) legacy mode to STM-64 (signal).
-
Provides clear comparison between older storage interface speeds and modern network transport rates.
-
Browser-based and easy to use with no installation required.
-
Supports benchmarking and integration analysis of legacy and modern systems.
Examples
-
5 IDE (DMA mode 2) converts to 0.066711677 STM-64 (signal).
-
10 IDE (DMA mode 2) converts to 0.133423354 STM-64 (signal).
Common Use Cases
-
Comparing legacy PATA/IDE data transfer speeds with high-speed synchronous digital signals.
-
Benchmarking legacy storage throughput relative to telecom network transmission rates.
-
Assisting in network and storage system diagnostics involving legacy devices and modern infrastructure.
Tips & Best Practices
-
Use conversion results mainly for comparison and historical analysis due to differing technologies.
-
Verify device mode configurations when diagnosing legacy storage performance.
-
Apply conversions in telecommunications planning to understand legacy device impact on network throughput.
Limitations
-
IDE (DMA mode 2) offers much lower throughput compared to STM-64, so conversion is mostly theoretical or comparative.
-
The converter suits legacy or embedded scenarios as IDE DMA is largely obsolete now.
-
STM-64 signals assume stable synchronous timing not present in IDE DMA transfers.
Frequently Asked Questions
-
What does IDE (DMA mode 2) stand for?
-
It is a Parallel ATA data transfer mode known as Multiword DMA mode 2 that allows direct memory access with lower CPU usage on legacy PATA/IDE devices.
-
What is STM-64 in data transfer?
-
STM-64 is a Synchronous Transport Module level‑64 signal in SDH with about 10 Gbit/s line rate, functionally equivalent to SONET OC‑192.
-
Why convert between IDE (DMA mode 2) and STM-64?
-
Conversion helps compare older storage device speeds against modern high-capacity synchronous transport signals for benchmarking and integration analysis.
