What is IDE (PIO mode 2)?

IDE (PIO mode 2) is a legacy ATA/IDE interface timing specification defining signal timing for CPU-driven data transfers without DMA, used in older IDE hard drives.

What does USB stand for and what is it used for?

USB stands for Universal Serial Bus, an industry-standard serial interface for data communication and power delivery between hosts like computers and various peripherals.

Why convert from IDE (PIO mode 2) to USB?

Converting helps compare legacy data transfer speeds to modern USB interfaces for diagnostics, compatibility checks, and data migration from older to current devices.
