What does IDE (UDMA mode 1) measure?

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

What does modem (2400) represent?

Modem (2400) denotes a data-transfer rate of 2400 bits per second, typical of early dial-up modem standards, and serves as a descriptive speed classification.

Why convert between IDE (UDMA mode 1) and modem (2400)?

Users convert between these units to compare or understand data transfer speeds of legacy PATA devices versus early dial-up modems, supporting historical benchmarking and compatibility assessments.
