USB disk EXFAT system format advantages and disadvantages

　　EXFAT System Format:

exFAT is a type format of u disk File system, exFAT is a continuation of FAT file system, that is, extended file allocation table, is a more suitable for Flash file system, is a new file system which is introduced to solve the limitation and disadvantage of FAT16/32. It does not have the NTFS format so many flash memory will not use more features, so the exFAT format file system is more suitable for a variety of mobile memory cards and U disk use.

　　Advantages of the EXFAT format:

1, enhance the desktop computer and mobile equipment interoperability capabilities;

2, the largest single file size up to 16EB (1EB=1024PB, 1PB=1024TB, 1TB=1024MB,16EB=16777216TB=17,179,869,184MB);

3, the cluster size can be as high as 32MB;

4, the same directory of the largest number of documents can reach 65 536;

5, support access control;

6, Support Tfat (WinCE early file system);

　　Disadvantages of the exFAT format:

exFAT compatibility is relatively poor, often unrecognized in XP systems, and in Win7 and WIN8 systems The problem is small.

When we format the U disk, we default to the FAT32 file system, however, it has limitations, if the use of the NTFS file system is also very hurt U disk, because the NTFS partition using the "log-type" file system, the need to record detailed reading and writing operations, will certainly be more damage to the flash disk chip, because to continue to read and write. So it is best to choose exFAT format File system when you format U disk.

After the introduction of the above, we believe that the exFAT format under the U disk has been a certain understanding of the bar, exFAT system format is a continuation of the FAT file system, although it is relatively poor compatibility, but in terms of capacity, interoperability, or support systems, It has an absolute advantage.
