What does IDE (PIO mode 4) represent?

IDE (PIO mode 4) is a CPU-controlled data transfer timing mode for ATA/IDE drives characterized by specific timing and handshaking protocols, mainly used for older hardware.

Why convert IDE (PIO mode 4) to gigabyte/second (SI def.)?

Converting allows comparison between legacy ATA device speeds and modern data transfer rates, useful for benchmarking and upgrade decisions.

Are the converted speeds actual performance measurements?

No, the conversion is based on theoretical maximum throughput and real speeds can vary due to CPU load and device condition.
