What does IDE (PIO mode 4) represent?

IDE (PIO mode 4) is a CPU-driven programmed input/output timing mode used in older ATA/IDE storage devices to control data transfers.

Why convert IDE (PIO mode 4) values to kilobyte per second?

Converting to kilobyte per second provides a standard data rate unit to compare and assess legacy storage device performance more easily.

Does 1 kilobyte always equal 1,024 bytes in this conversion?

No, this conversion uses the SI convention where 1 kilobyte equals 1,000 bytes, which differs from the binary definition of 1,024 bytes.
