What does IDE (UDMA mode 2) represent?

IDE (UDMA mode 2) is a Parallel ATA Ultra DMA mode that offers a maximum theoretical transfer rate of about 33.3 megabytes per second, commonly known as ATA/33.

What is meant by the USB unit in this conversion?

USB here represents the Universal Serial Bus standard, which includes various generations with nominal link-layer data rates ranging from around 12 Mbit/s up to 40 Gbit/s.

Is this conversion exact for real-world data transfer speeds?

No, the conversion is theoretical. Actual speeds depend on hardware limits, protocol differences, and specific USB standards, so results should be considered approximate.
