What is IDE (UDMA mode 4)?

IDE (UDMA mode 4), also called Ultra DMA/66, is a Parallel ATA transfer mode used in older PCs to achieve data transfer speeds up to approximately 66.7 megabytes per second.

Why convert IDE (UDMA mode 4) speeds to megabit/second?

Converting to megabit/second (SI definition) allows comparing legacy storage speeds with current networking and communication bandwidth standards.

Does this conversion reflect actual real-world data transfer rates?

No, the conversion represents theoretical maximum speeds; actual transfer rates may be lower due to hardware and system constraints.
