What does IDE (PIO mode 0) mean?

IDE (PIO mode 0) is a slow CPU-driven data-transfer timing mode used for compatibility with very old drives and controllers, involving the CPU reading and writing device registers.

What is SCSI (Async) data transfer mode?

SCSI (Async) refers to asynchronous data transfers using request and acknowledge handshakes without a shared clock, where throughput depends on device responses and bus arbitration.

Why convert from IDE (PIO mode 0) to SCSI (Async)?

Conversion helps compare legacy data transfer rates for performance analysis, diagnostics, and hardware compatibility in vintage and embedded computing contexts.
