What is IDE (PIO mode 2)?

IDE (PIO mode 2) is a legacy CPU-driven data transfer timing mode used by older IDE drives to manage data transfers without DMA.

Why convert IDE (PIO mode 2) speeds to gigabytes per second?

Converting to GB/s helps compare legacy hardware transfer performance with modern devices using a standardized, widely understood data rate unit.

Does this conversion consider differences between gigabyte definitions?

The conversion notes that SI and binary gigabyte definitions differ, so clarifying which standard applies is important when interpreting results.

Tips & Best Practices

Ensure clarity on whether gigabytes use SI or binary conventions when comparing results.
Use this conversion to contextualize older IDE interface speeds relative to modern data rates.
Recognize that IDE (PIO mode 2) represents slower, CPU-driven transfers not comparable to DMA or newer interfaces.
Double-check unit selections to avoid confusion between data transfer modes and units.

Limitations

Conversion applies only to legacy CPU-driven, non-DMA IDE (PIO mode 2) transfers, which have much lower throughput than modern technologies.
Differences between SI gigabyte and binary gibibyte definitions can affect interpretation of results.
The tool does not support other IDE modes or non-specified units outside the given scope.

Key Terminology

IDE (PIO mode 2): A legacy ATA/IDE interface timing standard defining programmed input/output (PIO) mode 2 transfer rates, used for CPU-driven data transfers.
Gigabyte/second (GB/s): A unit measuring data transfer rate equating to one gigabyte of data transmitted every second, with SI and binary definitions varying.
PIO: Programmed Input/Output, a data transfer method where the CPU manages data movement directly rather than using direct memory access (DMA).
