What is IDE (UDMA mode 4)?

IDE (UDMA mode 4), also known as Ultra DMA/66, is a Parallel ATA transfer mode that achieves theoretical data transfer rates of about 66.7 megabytes per second using an 80-conductor IDE cable.

How is gigabit per second (SI def.) different from gibibit per second?

Gigabit per second (SI def.) equals 10^9 bits per second, while gibibit per second uses a binary factor of 2^30. They quantify data rates differently and are not interchangeable.
