Exfat system format:

exfat is U disk A type of file system format, exfat is a continuation of the fat file system, that is, the extended file allocation table. It is a file system more suitable for flash memory and was launched to solve the limitations and shortcomings of fat16/32. A new file system. It does not have as much flash memory as the ntfs format and will not use more functions, so the exfat format file system is more suitable for various mobile memory cards and USB disks.

Advantages of Exfat format:

1. Enhance the interoperability between desktop computers and mobile devices

2. The maximum single file size can reach 16EB (1EB=1024PB, 1PB=1024TB, 1TB=1024MB, 16EB=16777216TB=17, 179, 869, 184MB)

If we choose the ntfs file system at this time, it will hurt the U disk because the ntfs partition uses a "logged" file system. , it is necessary to record detailed read and write operations, which will definitely damage the flash drive chip because it requires continuous reading and writing. Therefore, it is best to use the exfat format file system when formatting the USB disk.
