What is IDE (UDMA-33)?

IDE (UDMA-33) is a Parallel ATA data transfer mode for legacy IDE/ATA interfaces with a maximum theoretical burst rate of 33.3 MB/s.

How is a megabyte per second (SI def.) defined?

A megabyte per second (SI def.) represents 1,000,000 bytes transmitted each second, using decimal notation distinct from binary-based units.

Why convert IDE (UDMA-33) to megabyte/second (SI def.)?

Converting allows comparison of older PATA drive rates with modern data throughput metrics listed in standard decimal units.
