Application scenario
1. Data storage and transmission
The most basic use of U disk is to store and transfer data. It can transfer files from one computer to another and is especially useful when there is no Internet connection. For example:

① Back up important files.

②Move documents, pictures, videos, etc., between different computers or devices.

③ Temporarily store files for display or sharing on different occasions.

2. Install and restore the operating system

① Make a boot USB flash drive for installing the operating system.

② Used as a system recovery tool to restore the operating system.

③ Run some emergency diagnostic tools to help fix computer problems.

Advantages:

1. Convenience: USB flash drives are easy to use and carry, and are especially suitable for quickly transferring data between different devices without the support of a network or other external devices.
2. Data security: Compared with traditional storage media such as optical disks and disks, USB flash drives are more shock-resistant and drop resistant, and the risk of data damage is lower.
3. Space saving: USB flash drives do not require specialized storage devices, can easily store large amounts of data, and their small size does not take up additional space.
4. Efficient data transfer: USB flash drive supports fast data transfer, especially USB 3.0, 3.1 and USB-C interface USB flash drive, can greatly improve the file read and write speed, suitable for the fast transfer of large files.
5. Long-term storage: The USB flash drive uses flash technology, which is different from traditional hard disks and optical disks, and its data is stored for a long time, and it will not lose data because of long-term non-use.
6. Low cost: Compared with other storage devices, such as external hard disks, the price of U disks is relatively low, cost-effective, suitable for general users.
