What are some advantages of USB drives?

The main advantages of USB flash drives are their re-usability, flash memory, portability, and USB interface. Unlike optical media, data on USB drives can easily be changed, deleted, or added without the lengthy setup of data transfer for burning discs. Because of the flash memory, they do not have moving parts, which eliminates the chance of mechanical failure of component parts. They are portable, compact for their storage capabilities, and have minimal power requirements. Also, the universal availability of USB connections on computers allows the device to be plugged into any modern computer without the need for an intermediate interface.
