What size USB flash drive is suitable to buy?

U disks are mainly used to copy and back up files from the computer. As for the appropriate size, it also depends on what we are using the USB flash drive for.

Common usage scenarios of U disk:

1. Files exchanged during work are usually relatively small, no more than 1G, and then deleted in time.

2. The system boot disk is currently about 3.7G for WIN10, and a 4G U disk cannot fit in it. Then consider backing up some common software, at least 8G.

3. Medium-sized file exchange, such as copying a virtual machine, a few movies, etc., 64G and 128G are suitable.

4. For larger file exchanges, such as migrating an entire work project, it is recommended to use a 512G or mobile hard drive.

5. For file backup, if the computer hard drive is not enough, you must consider a 2T or above mobile hard drive.

32G or 64G is enough, no matter how large it is, it is not cost-effective.
