What is IDE (PIO mode 2)?

It is a legacy ATA/IDE interface timing mode that defines data transfer timing and max performance for CPU-driven, non-DMA transfers on older IDE storage devices.

What does T3 (payload) mean?

T3 (payload) refers to the user-data bandwidth available on a T3/DS3 telecommunications circuit after protocol overhead is excluded.

Why convert between IDE (PIO mode 2) and T3 (payload)?

This conversion helps compare legacy storage transfer modes with telecommunications data rates to assist in diagnostics and capacity planning.
