The difference between a card reader and a USB flash drive

Card Reader is a card reading device that needs to be used with a matching memory card (storage medium), including our common SD card, TF card, CF card, etc. It can be simply understood that the card reader is the bridge between the memory card and the computer equipment, responsible for the transmission and docking of the two.

The U disk (USB flash disk) is called a flash disk, which is an integration of a flash memory medium and a data interface. The storage medium does not support assembly and disassembly, and the data terminal is connected through the USB interface, which is plug and play.

The transmission speed of the card reader mainly depends on the data interface and the reading speed of the memory card, while the transmission speed of the U disk mainly depends on the data interface and the reading speed of the flash media of the U disk.
