Both network disk and USB flash drive can store data, but there are great differences. The network disk is not a physical hard disk, but a storage space on the network. It is a logical existence, and the U disk is an entity that needs to be plugged into the USB port of the computer before it can be used. Using USB flash drive to transmit data does not need network support, but it must have network support.
The name of USB flash drive comes from a new storage device produced by Netac, called USB flash drive, which is connected by USB interface. After the USB interface is connected to the computer host, you can exchange the data of the U disk with the computer. Later, the equipment with similar technology has been patented by Netac.
