What is IDE (PIO mode 3)?

IDE (PIO mode 3) is a programmed I/O data transfer mode for Parallel ATA/IDE devices, controlled by the CPU and defined by ATA standards, with a max throughput of about 11.1 MB/s.

What does T4 (signal) represent?

T4 (signal) is a high-order trunk signal in the North American T-carrier system, corresponding to the DS4 rate, carrying multiplexed lower channels at roughly 274.176 Mbps.

Why convert from IDE (PIO mode 3) to T4 (signal)?

Comparing speeds between older IDE drives and T-carrier based trunk lines

Tips & Best Practices

Remember that IDE throughput is in megabytes per second while T4 rates are in megabits per second, so watch units carefully
Use this tool primarily for historical, testing, or compatibility analysis rather than modern application sizing
Validate conversions with appropriate domain knowledge given the legacy nature of these technologies
Understand that theoretical rates may differ from actual performance due to overheads and environment

Limitations

IDE (PIO mode 3) and T4 (signal) use different measurement units (MB/s vs Mbps), requiring attention during conversion
Theoretical maximum speeds may not reflect real-world sustained transfer rates
Both units correspond to legacy technologies with limited current practical use
Conversion does not account for overhead factors or signal quality variations
