What does IDE (PIO mode 2) represent?

It is a legacy ATA/IDE interface timing spec defining CPU-driven data transfer speeds without DMA, mainly used in older hard drives and optical drives.

What is a terabit per second (SI definition)?

A terabit per second is a data rate unit meaning one trillion (10^12) bits are transferred each second, based on the decimal SI prefix 'tera'.

Why convert IDE (PIO mode 2) speeds to terabit/second?

To compare old IDE hardware speeds with modern high-capacity data transfer rates for diagnostics, compatibility, or technical analysis.
