What does IDE (PIO mode 0) represent in data transfer?

IDE (PIO mode 0) is the slowest CPU-driven ATA data transfer mode, used primarily for compatibility with old drives and relies on the CPU for reading and writing data.

Why convert IDE (PIO mode 0) speeds to USB?

Converting these speeds helps compare legacy data transfer rates to modern USB standards and understand compatibility for data recovery or hardware upgrade purposes.

Is the conversion exact and applicable to all USB versions?

No, the conversion is approximate and does not account for the variety of USB versions or real-world performance differences.
