What is IDE (UDMA mode 4)?

IDE (UDMA mode 4) is a Parallel ATA transfer mode using Ultra DMA protocol with a theoretical speed of about 66.7 megabytes per second, common in late 1990s and early 2000s PCs.

What does gigabyte/second (SI definition) mean?

It represents a data transfer rate where 1 gigabyte equals 10^9 bytes transferred every second, using decimal-based SI units.

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

To express legacy IDE transfer rates in modern units for consistent comparison and benchmarking across different technology generations.
