What is IDE (PIO mode 4)?

IDE (PIO mode 4) is a CPU-controlled timing mode for ATA/IDE drives used in older computers, defining data transfer timing rather than an exact throughput.

What does STS3 (payload) represent?

STS3 (payload) is the portion of a SONET STS-3 or OC-3 frame dedicated to carrying user data, excluding framing and overhead.

Why convert from IDE (PIO mode 4) to STS3 (payload)?

Converting helps compare or relate legacy IDE data transfer modes with modern SONET payload capacities, aiding diagnostics, network planning, and system integration.

Common Use Cases

Diagnosing or benchmarking legacy ATA/IDE storage devices in retro-computing environments
Provisioning and capacity planning for SONET OC-3 telecommunications circuits
Measuring payload capacity for billing and SLA analysis in leased-line services
Ensuring compatibility in industrial systems using older ATA timing modes integrated with modern optical transport

Tips & Best Practices

Use this tool primarily for estimation and performance comparison rather than exact data throughput calculations
Consider overhead and protocol differences inherent to each format before interpreting conversion results
Apply conversions during system diagnostics and upgrade assessments involving legacy and telecom hardware
Verify results with domain-specific tools if precise data rates are critical

Limitations

IDE (PIO mode 4) represents a timing mode and not a precise physical data rate, so conversions are approximate
STS3 (payload) accounts for SONET framing overhead, reflecting user-data capacity rather than total line rate
Due to differing protocols and contexts, use conversions mainly for benchmarking and estimations
