What does IDE (UDMA mode 2) represent?

IDE (UDMA mode 2) is an Ultra DMA transfer mode for legacy Parallel ATA interfaces that allows data transfers up to approximately 33.3 megabytes per second.

Why convert IDE (UDMA mode 2) to byte/second?

Converting to byte/second helps quantify data transfer rates in standardized units common to modern storage devices and facilitates performance comparison and troubleshooting.

Does this conversion reflect actual transfer speeds?

No, the conversion represents theoretical maximum throughput; actual transfer rates may be affected by system hardware, cabling, and overhead.
