This article mainly introduces the U disk in the fat32 and ntfs format what is the difference, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

We often use flash drives in our daily life. The main formats of USB disk are fat32 and ntfs. For these two USB disk formats, I believe many users do not know the difference between them.

U disk FAT32 format

The FAT32 file system FAT32 uses 4 bytes (that is, 32 bits) of space to represent the case of each sector (Sector) profile, so it is called FAT32.

The FAT32 file system can relocate the root directory and use backup copies. In addition, the startup record of the FAT32 partition is included in a structure containing critical data, which reduces the possibility of computer system crash. More flexible.

The root folder on the FAT32 partition is a normal cluster chain, so it can be located anywhere on the drive. The previous limit on the number of root folders no longer exists. In addition, you can disable file allocation table mirroring so that you can make a copy of the file allocation table instead of making the first file allocation table active. These features allow you to dynamically resize FAT32 partitions.

Note, however, that although FAT32 is designed to allow this feature, Microsoft's own partitioning software does not support this feature and requires the use of third-party partitioning software. Use FAT32 to format 2GB USB disk, the cluster is smaller.

FAT32's shortcomings although the support for the maximum partition capacity above, the maximum partition capacity of FAT32 2TB is still not out of date, but FAT32 can only store a single file of the largest 4GB, so FAT32 can not store CD-ROM ISO images, high-definition video, a variety of graphics files, and so on, which is its fatal malpractice.

NTFS format of USB disk

The NTFS file system NTFS (New Technology File System) is the file system of the Windows NT core and advanced server network operating system environment. The goal of NTFS is to provide higher reliability than FAT32 and to eliminate limitations in the FAT file system. In addition to supporting larger partitions, larger files, and more saving hard disk space, the NTFS file system also provides many features that the FAT file system can't imagine.

Mainly include: long file name, compressed partition, event tracking, file index, high fault tolerance, data protection and recovery, encrypted access. NTFS supports files larger than 4GB as NTFS partition has become the absolute mainstream format of computer disks, XP, vista, Win7 will format the partition as NTFS system by default, so the advantages and features of NTFS need to be emphasized more, it can be said that NTFS is currently the best disk file system, but why U disk and various storage cards rarely use NTFS file system? The following is the official website of the computer store to talk about NTFS's defects in flash memory.

Although NTFS has many advantages, these are designed for traditional mechanical hard drives and may not be suitable for emerging Flash flash memory materials. NTFS partition is a "journal" file system, because to record the detailed read and write operations of the disk, the flash storage media such as U disk will cause a greater burden, such as the same access to a file or directory, the number of read and write times on the NTFS system will be more than FAT32, in theory, the NTFS format U disk is easier to damage, and the partition under 400MB is also more wasteful than FAT16.

These additional functions of NTFS will cause varying degrees of damage to both SSD hard drives and USB drives, so the new generation of Windows 7 operating system is specifically optimized for SSD to reduce the number of reads and writes and the generation of fragments by various means. For U disk, the bandwidth of USB is limited, and frequent read and write occupation of NTFS file system will degrade disk performance. Therefore, Microsoft has developed ExFAT file system specifically for mobile storage devices.

Thank you for reading this article carefully. I hope the article "what's the difference between fat32 and ntfs format in U disk" shared by the editor will be helpful to everyone. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
