What Is This Tool?
This converter allows users to translate data transfer speeds from STS3c (signal), a telecommunications SONET signal with a 155.52 Mbit/s rate, into IDE (UDMA mode 3), which is a legacy Parallel ATA transfer mode with speeds around 44.4 MB/s. It helps relate high-bandwidth telecom signals to legacy computer storage interfaces.
How to Use This Tool?
-
Enter the value in STS3c (signal) units you want to convert.
-
Select IDE (UDMA mode 3) as the target unit.
-
Click convert to see the equivalent transfer rate in IDE (UDMA mode 3).
-
Use results to compare telecom data rates to legacy storage speeds.
Key Features
-
Converts STS3c (signal) data rates to IDE (UDMA mode 3) units easily.
-
Based on precise conversion rate linking telecom signals to legacy PATA speeds.
-
Useful for comparing throughput between distinct technologies.
-
Browser-based and straightforward to operate.
Examples
-
5 STS3c (signal) converts to 1.944 IDE (UDMA mode 3).
-
10 STS3c (signal) equals 3.888 IDE (UDMA mode 3).
Common Use Cases
-
Planning telecom backbone circuits with OC-3c/STS-3c capacity specifications.
-
Comparing telecom SONET throughput to PATA hard drive speeds.
-
Configuring or benchmarking legacy PATA/IDE drive performance.
-
Troubleshooting or refurbishing systems that include older storage technologies.
Tips & Best Practices
-
Always consider the difference in units—STS3c uses Mbit/s while IDE uses MB/s.
-
Use the converter to get approximate throughput comparisons across technologies.
-
Check for system-specific overheads when applying conversion results to practical setups.
-
Remember legacy nature of IDE (UDMA mode 3) when interpreting results.
Limitations
-
Conversion compares fundamentally different technologies with distinct physical layers.
-
STS3c measures network data transport in bits per second; IDE (UDMA mode 3) measures storage interface throughput in bytes per second.
-
Transfer rates may not reflect real-world throughput due to overhead and system variations.
-
IDE (UDMA mode 3) is outdated and has limited contemporary application.
