What is IDE (DMA mode 2)?

IDE (DMA mode 2) is a Multiword DMA transfer mode for legacy Parallel ATA devices that allows direct data movement between the device and system memory with reduced CPU usage.

Why convert IDE (DMA mode 2) to megabit per second (SI)?

Converting to megabit per second (SI) standardizes the measurement of data transfer rates, helping benchmark and compare legacy device performance with modern network speeds.

Does this conversion apply to modern storage technologies?

No, this conversion specifically applies to the IDE (DMA mode 2) legacy transfer mode and does not reflect the transfer rates of current storage technologies.
