What does IDE (PIO mode 4) represent?

IDE (PIO mode 4) is a CPU-controlled timing mode for ATA/IDE storage devices, indicating a legacy data transfer method with a certain maximum throughput.

Why convert IDE (PIO mode 4) to GB/s?

Converting to GB/s helps quantify legacy drive speeds in a modern unit, aiding performance comparisons, diagnostics, and upgrade decisions.

Does 1 GB always mean the same number of bytes?

No, 1 GB can refer to 10^9 bytes in decimal units or 2^30 bytes in binary units (Gibibytes); specifying the convention is important.
