What is IDE (PIO mode 3)?

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

What does kilobyte/second (SI def.) mean?

A kilobyte per second in SI terms is a data transfer rate equal to 1000 bytes per second, distinct from binary-based units like kibibytes per second.

Why convert IDE (PIO mode 3) to kilobyte/second (SI def.)?

Converting allows users to express legacy device transfer rates in a standard unit to facilitate easier comparison with modern data transfer speeds.
