What does IDE (UDMA mode 1) mean?

It is an Ultra DMA transfer mode for the Parallel ATA interface, providing a theoretical max transfer rate of about 25 MB/s for older PATA devices.

Why convert IDE (UDMA mode 1) rates to megabit per second?

To compare or communicate data rates between legacy hardware speeds and modern network bandwidth measurements.

Is the converted speed an exact representation of real performance?

No, IDE (UDMA mode 1) speeds are theoretical maximums and may not reflect actual sustained throughput.
