What does IDE (UDMA mode 2) represent?

It is an Ultra DMA transfer mode for Parallel ATA interfaces providing about 33.3 megabytes per second transfer speed, used for legacy PATA devices.

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

To express legacy interface speeds in fundamental data rate units that facilitate comparison with modern communication rates.

Can actual transfer rates reach the theoretical maximum of IDE (UDMA mode 2)?

Not always; real transfer rates depend on hardware, firmware, and cable quality which may limit performance.
