What does IDE (PIO mode 4) represent?

It is a CPU-controlled timing mode for IDE/ATA drives defining data transfer rates and handshaking protocols, mostly used in older systems.

Why convert IDE (PIO mode 4) to byte/second?

Converting to byte/second standardizes the data rate for comparing legacy device performance with modern benchmarks.

Are conversions precise for real-world speeds?

No. The conversion reflects theoretical maximum throughput; actual speeds may be lower due to hardware and overhead factors.
