What does IDE (UDMA mode 0) represent?

IDE (UDMA mode 0) refers to the Ultra DMA transfer mode 0 for Parallel ATA devices, specifying timing and a nominal max raw data transfer rate of about 16.7 MB/s.

What is measured by the E.P.T.A. 1 (payload) unit?

E.P.T.A. 1 (payload) denotes the size of user data within a single E.P.T.A. 1 frame or packet, focusing on payload length rather than protocol overhead.

Why convert from IDE (UDMA mode 0) to E.P.T.A. 1 (payload)?

Converting helps translate legacy throughput rates into protocol-specific payload units, aiding bandwidth management, diagnostics, and buffer sizing in mixed-protocol systems.
