What does IDE (PIO mode 2) represent?

It is an ATA/IDE interface timing mode defining CPU-driven data transfer cycles between host and storage devices, used by older drives.

What is modem (1200)?

A legacy designation for modems achieving approximately 1,200 bits per second in early dial-up communication systems.

Can this conversion reflect actual data throughput exactly?

No, because IDE and modem units represent different transfer methods and do not account for overhead or inefficiencies.
