What is IDE (PIO mode 0)?

It is an ATA/IDE Programmed Input/Output timing mode that defines the slowest CPU-driven data transfer method for legacy storage devices.

Why convert IDE (PIO mode 0) to byte/second?

Converting allows users to measure and compare legacy IDE transfer rates using a standard digital throughput unit commonly used today.

Is IDE (PIO mode 0) still used in modern systems?

No, it is mostly obsolete and used only for compatibility with very old drives and hardware.

How to Convert from IDE (PIO mode 0) to Byte/second [B/s]

Convert IDE (PIO mode 0) data transfer rates to byte/second (B/s) for evaluating legacy storage device performance and compatibility.
