What does Modem (14.4k) measure?

Modem (14.4k) refers to a dial-up modem's maximum raw data transfer rate of 14.4 kilobits per second over analog telephone lines.

What is IDE (UDMA-66)?

IDE (UDMA-66) is a Parallel ATA transfer mode specifying a maximum theoretical burst data rate of 66.7 megabytes per second for legacy PATA storage devices.

Why is the conversion between these units limited?

Because Modem speeds are bit rates over serial analog lines while IDE (UDMA-66) rates represent burst transfer bytes per second on storage devices, their direct comparison is theoretical.
