What is IDE (DMA mode 2)?

IDE (DMA mode 2) is a Parallel ATA data transfer mode that allows IDE devices to move data directly to or from system memory with less CPU load, typical in legacy PATA/IDE interfaces.

What does T1C (payload) represent?

T1C (payload) denotes the user-data portion of a T1 digital carrier after removing framing and control overhead, indicating the effective throughput available for user communication.

Can this tool be used for modern storage or networking equipment?

No, this converter is intended for legacy IDE and T1 line throughput comparisons and is not applicable to modern hardware or network technologies.

Tips & Best Practices

Use this converter primarily for legacy hardware and network environments
Remember that IDE (DMA mode 2) and T1C (payload) measure related but different contexts—storage interface speed vs. telecom payload
Verify assumptions about overhead and framing when interpreting results for T1C payload
Combine conversion results with other diagnostics for comprehensive performance evaluation
Avoid applying this conversion for modern storage or networking equipment

Limitations

Direct conversion assumes a comparative throughput equivalence but does not account for protocol overhead differences
T1C (payload) is a non-standard telecommunications term that may vary with framing overhead assumptions
Conversion is specific to legacy technologies and may not apply to current hardware or network standards
Does not reflect timing variations or real-world transfer conditions between IDE DMA and T1 payload
