What is IDE (PIO mode 4)?

IDE (PIO mode 4) is a CPU-driven timing mode for ATA/IDE drives that controls data transfer timing and has a theoretical maximum throughput of about 16.7 MB/s.

Is H11 a standard data transfer unit?

No, H11 is not a recognized or standard unit for data transfer and lacks formal definition or widespread acceptance.

Why convert IDE (PIO mode 4) to H11?

Converting IDE (PIO mode 4) to H11 can help compare legacy IDE transfer speeds against other units for benchmarking or compatibility assessments in retro-computing.
