What is IDE (PIO mode 3)?

IDE (PIO mode 3) is a CPU-driven parallel ATA transfer mode with a maximum theoretical throughput of about 11.1 megabytes per second, mostly used in legacy storage devices.

What does modem (300) mean?

Modem (300) refers to a data transfer rate of 300 bits per second from early analog dial-up modems, commonly used in historical low-speed serial or telephone modem communications.

Why convert from IDE (PIO mode 3) to modem (300)?

This conversion helps compare or document data rates between fast legacy storage devices and early low-speed modem links, especially useful in retrocomputing and historical analysis.
