What is IDE (UDMA mode 4)?

IDE (UDMA mode 4), also called Ultra DMA/66, is a Parallel ATA transfer mode in the IDE/ATA standard providing a maximum theoretical throughput around 66.7 megabytes per second.

What does gigabit per second measure?

A gigabit per second (Gb/s) indicates a data transfer rate of one billion bits transmitted every second, commonly used for network bandwidth and communication link speeds.

Why convert IDE (UDMA mode 4) to Gb/s?

Converting helps compare legacy storage device speeds with modern network throughput for integration, benchmarking, and performance evaluation purposes.
