What is IDE (PIO mode 3)?

It is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE devices, mainly used in legacy systems, with a theoretical maximum throughput around 11.1 MB/s.

What does E.P.T.A. 2 (payload) measure?

It measures the amount of user/application data contained in a single message of the E.P.T.A. 2 data transfer protocol, defined by the protocol’s own specifications.

Is the conversion from IDE (PIO mode 3) to E.P.T.A. 2 universally accurate?

No, the conversion assumes a fixed rate, but actual payload sizes and throughput can vary depending on specific implementations and protocol definitions.
