What is IDE (PIO mode 3)?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode used in older Parallel ATA storage devices, defined by ATA standards.

What does T1 (payload) represent?

T1 (payload) indicates the usable data throughput of a T1 line, totaling 1.536 Mbps for 24 channels each at 64 kb/s, excluding framing overhead.

Why convert IDE (PIO mode 3) to T1 (payload)?

Converting helps compare data transfer rates from legacy storage interfaces to telecom bandwidth units, useful in retrocomputing and network planning.
