What does IDE (PIO mode 1) mean?

IDE (PIO mode 1) is a legacy data transfer mode where the CPU controls each transfer cycle for PATA devices, resulting in moderate throughput with higher CPU overhead.

Why convert IDE (PIO mode 1) data rates to USB?

Converting allows comparison between older PATA device transfer rates and modern USB standards, which is helpful for diagnostics, benchmarking, and technology upgrades.

Are the converted transfer rates exact values?

No, the converted rates reflect nominal theoretical values and may not represent sustained real-world transfer speeds due to hardware variations.
