What does IDE (PIO mode 3) represent?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for older Parallel ATA/IDE storage devices defined by ATA standards, with a maximum theoretical throughput around 11.1 megabytes per second.

What is meant by T3 (payload)?

T3 (payload) indicates the actual user-data throughput available on a T3/DS3 telecommunications line after removing overhead from framing, signaling, and protocols, with a nominal line rate of 44.736 megabits per second.

Why convert from IDE (PIO mode 3) to T3 (payload)?

Converting between these units helps compare legacy IDE storage data rates to telecommunications user-data throughput values, supporting planning and analysis in industries such as retrocomputing, ISP provisioning, and networking.

Tips & Best Practices

Always consider the difference in units: IDE throughput is in megabytes per second, while T3 payload is in megabits per second.
Use this converter as an approximate comparison tool, not for precise real-world performance measurement.
Account for protocol overhead and hardware limitations when applying converted throughput values in planning.
Verify units carefully to avoid confusion between raw line rates and user payload rates in telecom circuits.
Refer to examples to understand typical conversion results before applying in your context.

Limitations

Conversion is based on theoretical maximum throughput and ideal conditions, which may differ from actual performance.
Differences in protocol overhead, framing, and hardware constraints mean results serve as rough comparisons.
Units differ fundamentally: IDE uses megabytes per second while T3 payload uses megabits per second.
The tool does not account for real-world inefficiencies or network protocol variations in data transfer.

Key Terminology

IDE (PIO mode 3): A programmed I/O transfer mode driven by the CPU for legacy Parallel ATA/IDE devices, offering a theoretical maximum throughput near 11.1 MB/s.
T3 (payload): The user-data throughput available after overhead on a T3/DS3 digital telecom circuit, distinct from the nominal line rate of 44.736 Mb/s.
Programmed I/O (PIO): A method of data transfer where the CPU controls and manages each data operation rather than using direct memory access.
Payload: The portion of a telecommunications signal's bandwidth dedicated to actual user data after subtracting framing, signaling, and protocol overhead.
