What is IDE (UDMA-33)?

IDE (UDMA-33) is a legacy Parallel ATA (PATA) data transfer mode that uses direct memory access, providing a theoretical maximum burst rate of 33.3 MB/s.

Why convert IDE (UDMA-33) to megabyte per second?

Converting to MB/s translates legacy transfer rates into a modern, widely understood format, aiding benchmarking and performance comparison.

Can actual transfer speeds be lower than the conversion results?

Yes, actual speeds may be less due to hardware limitations, cable quality, and system overhead, not reflecting the theoretical maximum.
