What is IDE (PIO mode 3)?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE storage devices, with a theoretical maximum speed of about 11.1 MB/s.

How does this converter handle gigabyte definitions?

This converter uses the decimal SI definition where 1 GB equals 10^9 bytes; be aware some systems use binary gigabytes (gibibytes).

Why convert IDE (PIO mode 3) speeds to GB/s?

Converting to GB/s helps compare older IDE device speeds with modern data transfer rates for benchmarking and system planning.

Planning and benchmarking data transfer rates in IT and industrial environments

Tips & Best Practices

Confirm the gigabyte definition used when comparing rates (decimal vs binary)
Use this conversion for theoretical maximum speeds, as real-world rates may differ
Apply this tool for legacy devices rather than modern DMA-based systems
Always cross-check converted values when planning system performance

Limitations

IDE (PIO mode 3) speeds represent theoretical maxima and are CPU-driven, so actual speeds can be slower
The GB/s unit here assumes the decimal SI gigabyte definition (1 GB = 10^9 bytes)
Modern hardware predominantly uses DMA and faster transfer modes, limiting IDE (PIO mode 3) relevance
