What does Modem (28.8k) represent?

Modem (28.8k) is an informal label for a 28.8 kilobits per second data transfer rate typical of dial-up modem connections over analog telephone lines.

What is IDE (UDMA mode 1)?

IDE (UDMA mode 1) is an Ultra DMA transfer mode for PATA devices providing a theoretical maximum transfer rate of about 25 MB/s.

Why convert between these units?

Conversion helps compare and understand differences between slow dial-up modem speeds and faster legacy IDE storage interface rates.

How to Convert from Modem (28.8k) to IDE (UDMA mode 1)?
