What is the difference between exFAT format and FAT, FAT32, NTFS

FAT32 is the first to appear, high compatibility, but not high security, NTFS is used in more than 2000 systems, high security, can encrypt files, but used in disks greater than 2G! And ExFAT is officially in between, NTFS reads and writes back and forth too frequently, and is used on a USB flash drive to reduce the service life, and ExFAT just complements this point! If it is a USB flash drive of more than 2G, it is recommended to use ExFAT or FAT32 If it is a hard disk of more than 2G, it is recommended to use NTFS!

1. The maximum size of a single file supported by the system is different

fat:2gb、fat32:4gb、ntfs：256tb、exfat:16eb;

2. The maximum formatting capacity of the file system is different

FAT: 2 GB, FAT32: 2 TB (32 GB for a single NT core system), NTFS:

2TB-256TB (GPT partition format can be larger due to MBR), EXFAT: 64ZB (theoretical, currently supported up to 128PB);

3. The size of the cluster is different (according to the capacity of the storage device disk, flash card and hard disk, the size of the cluster can be different to make the storage space get the most efficient application);

Maximum cluster: FAT: 32KB, FAT32: 64KB, NTFS: 64KB, EXFAT: 32768KB;

4. The supported operating systems are the same;

fat:dos、windows 95、linux；FAT32: After Win95 OSR2; ntfs：

Windows 2000 onwards; ExFAT: Windows CE6, Vista SP1, Windows 7 or later.

<>1. What does exFAT mean? exFAT is a type of file system of USB flash drive, exFAT is a continuation of the FAT file system, that is, the extended file allocation table, is a file system more suitable for flash memory, it is to solve the FAT32 and other files that do not support 4G and larger files and launch a new file system. Compared with NTFS file system and FAT32 file system, ExFAT file system can solve many problems such as flash memory such as USB flash drive.

2. The difference between ExFAT and FAT32: ExFAT is a new file system launched to solve the limitations and shortcomings of FAT16 32. It doesn't have as much flash memory as the NTFS format, so the ExFAT format file system is more suitable for all kinds of removable memory cards and USB flash drives.

3. Advantages and disadvantages of the format: The advantage of ExFAT is that it can be expanded to a larger floppy disk size, from 32GB of FAT32 to 256TB; ExFAT consumes less floppy disk space than NTFS, and experiments have found that 4GB of flash memory uses up floppy disk space just after formatting to NTFS, while only 96KB is used when formatted to ExFAT. However, the disadvantage is that some devices (such as PDA, DC) will not be able to use flash memory cards in ExFAT format; It can't support some system acceleration after WinVista well; For XP, systems without KB955704 will not be able to recognize the ExFAT format.

Those theories and all that are incomprehensible to people can't understand. To put it simply, fat32 will generate a record when there is an error in the partition. Then remember that there is a mistake on that point.

When you store something again, it won't be there. However, due to technical issues, FAT32 does not support files larger than 4GB in a single file.

NTFS can store a single file larger than 4GB, but it does not have a recording function, if there is an error in the partition, then the new data is stored in the error area. It can well be imagined. All that comes is file corruption is loss.

The error areas mentioned above are only soft errors and can be fixed.

ExFAT is equivalent to combining the above two advantages. That is, you can store a single file of more than 4GB (and the theoretical value is quite large), and it will also record errors...

This is the easiest way to understand.

NTFS is more secure than FAT32 and access rights can be set. In addition, NTFS is less prone to fragmentation during use.

NTFS is safer than FAT32, so it is the most commonly used one now.

Take you to understand the difference between hard disk FAT32 and EXFAT, if you don't understand, you can take a look!

What does USB flash drive format mean? What is the difference between FAT32, NTFS, and ExFAT formats?

NTFS has a great impact on the life of flash memory, and the access speed will be greatly reduced after the USB flash drive is formatted to EXFAT, which will affect the service life.

Distinguish. 1. The scope of application is different.

EXFAT: Suitable for flash drives (USB flash drives).

NTFS: Suitable for disks (HDDs, SSDs).

2. The maximum space is different.

ExFAT: Supports up to 16EB (currently 256GB).

NTFS: up to 256 TB (MBR).

3. Security is different.

exfat: Microsoft's file system designed for flash memory (USB flash drive, memory card) flash memory devices, with good compatibility.

NTFS: Safety, ease of use, and stability.

4. The U disk uses different groups of fingers for the life of the ear base.

EXFAT: The first choice for mobile devices such as USB flash drives, with a long service life.

NTFS: It is not recommended to use NTFS for USB flash drives, which will greatly shorten the service life.

5. The use system is different.

ExFat: Works on both Windows and Mac.

NTFS: For Mac users, it cannot be used directly, and Mac users need to use third-party software to write to the NTFS file system.

The partition on Linux is very different from the partition on Windows, NTFS on Windows may be compared with the early file format on Linux, the biggest difference is that the Windows partition is tightly arranged files, the performance may be high at the beginning and then it will obviously feel slow, there are too many fragments, and there are many places left in advance on Linux to avoid fragmentation, and the performance is uniform XFS performance is more balanced, but the performance of small files is particularly bad, but I have also heard.

Fat fat32 does not need to be compared, it is directly out of the game compared with ntfs, the ext file system supports link (hard chain or soft chain, see ln command); It doesn't generate a lot of fragments as quickly as NTFS does; Support more types of files (such as device files under dev, virtual files under proc, socket files, etc.) ext3 and ntfs are log systems, which can provide fast and correct recovery of sudden power failure, ext3 to remove the log function is ext2, the efficiency will be improved ext There is also a significant advantage, that is, open source, so it is more widely used on non-Windows systems, although the total end users may not be as many as Windows, However, most embedded systems use open source file systems, and if you want to use FAT, you have to pay Microsoft for each individual product (even if FAT is so indiscriminate) [S:78] If the system is Linux, it is impossible to choose NTFS as the file system, and in addition to the cost problem, many of the functional requirements of Linux cannot be met by NTFS; Conversely, Windows can't use ext, so it's not measured in terms of system dependencies.

No advantages are in sight. Slow to death. ext3 I never use it. ext4 is said to be good, but personal use is of course the fastest and best, and it doesn't matter what other security is. xfs jsf reserifs

I've heard that ext seems to be getting faster and faster. Fat NTFS, on the other hand, is not so clear.
