What does IDE (PIO mode 1) mean in data transfer?

IDE (PIO mode 1) is a CPU-controlled data transfer mode used by legacy PATA devices, characterized by low-to-moderate throughput and higher CPU overhead.

Why convert IDE (PIO mode 1) to gigabyte/second (SI def.)?

Converting to gigabyte/second (SI) allows users to compare legacy data transfer rates with modern standardized throughput units for storage and network devices.

Can this conversion reflect peak data transfer speeds of modern devices?

No, the conversion is based on IDE (PIO mode 1) characteristics and does not represent the peak performance achievable by modern storage or networking technologies.
