What does IDE (UDMA-33) stand for?

IDE (UDMA-33) refers to a Parallel ATA data transfer mode, also known as ATA/33 or Ultra DMA mode 4, supporting burst transfer rates up to 33.3 MB/s.

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

Gigabit/second (SI def.) uses a decimal definition of 10^9 bits per second, whereas gibibit/second is a binary-based unit using 2^30 bits.

Why convert IDE (UDMA-33) to gigabit/second?

Converting to gigabit/second helps compare legacy PATA drive speeds with modern data transfer rates commonly used in networking and communications.
