What does IDE (UDMA mode 0) represent in data transfer?

It is an Ultra DMA transfer mode for Parallel ATA (PATA) devices defining interface timing and a nominal maximum raw data transfer rate of about 16.7 megabytes per second.

How does megabyte per second (SI) differ from other similar units?

A megabyte per second (SI) means 1,000,000 bytes transferred per second, which is distinct from binary-based units like mebibyte per second that use powers of 2.

Why convert IDE (UDMA mode 0) to megabyte/second (SI)?

To translate legacy PATA transfer rates into standardized modern units for easier comparison, troubleshooting, and system upgrades.
