What does IDE (UDMA mode 4) represent?

IDE (UDMA mode 4) is a Parallel ATA transfer mode with a theoretical max throughput of about 66.7 megabytes per second, requiring an 80-conductor IDE cable for reliable signaling.

Modem (300) denotes a data transfer rate of 300 bits per second from early analog dial-up modem standards, commonly used in vintage communication contexts.

Why convert IDE (UDMA mode 4) to modem (300)?

Users convert between these units to compare or relate modern legacy IDE transfer speeds to early modem rates for benchmarking, documentation, and historical reference.
