What does USB stand for and represent?

USB stands for Universal Serial Bus and is a standard interface used for data communication and power delivery between host devices and peripherals.

What is IDE (PIO mode 3)?

IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode defined for Parallel ATA/IDE storage devices, with a theoretical maximum throughput around 11.1 MB/s.

Why would I convert USB rates to IDE (PIO mode 3)?

Users convert these rates to compare modern USB transfer speeds with older IDE interfaces, which helps in compatibility analysis and retrocomputing tasks.
