What does IDE (UDMA mode 2) represent?

IDE (UDMA mode 2) is an Ultra DMA mode for PATA interfaces offering a maximum theoretical transfer speed of about 33.3 megabytes per second.

How is a kilobyte per second defined in SI terms?

A kilobyte per second (SI definition) equals 1,000 bytes transmitted or processed each second, differing from binary units based on 1024 bytes.

Why convert IDE (UDMA mode 2) rates to kilobyte/second (SI def.)?

Converting to kilobyte/second (SI) helps standardize legacy data rates for easier comparison with modern transfer speeds and performance benchmarks.
