What is the difference between the FAT32 and NTFS formats on the USB flash disk

U On the plate fat32 and ntfs What's the difference between formats

This article mainly introduces U On the plate fat32 and ntfs What's the difference between formats , It has certain reference value , Interested friends can refer to , I hope you will gain a lot after reading this article , Now let Xiaobian take you to know .

  In daily life , We often use U disc .U The main formats of the disk are fat32 and ntfs Two kinds of . For both U Disk format , I believe many users do not know the difference between them .

                                             

u disc FAT32 Format

FAT32 file system FAT32 Use 4 Bytes ( That is to say 32 position ) To represent each sector (Sector) In the case of configuration files , So it's called FAT32.

FAT32 File systems can relocate the root directory and use backup copies . in addition FAT32 The boot record of the partition is contained in a structure containing key data , Reduce the possibility of computer system crash . More flexibility .

FAT32 The root folder on the partition is an ordinary cluster chain , So it can be anywhere on the drive . The previous limit on the number of root folders no longer exists . Besides , You can disable file allocation table mirroring , This allows you to make a copy of the file allocation table instead of making the first file allocation table active . These features allow you to dynamically reset FAT32 Size of partition .

But be careful , although FAT32 The design of the allows this function , However, Microsoft's own partition software does not support this function , Third party partition software is required . Use FAT32 format 2GB U disc , Smaller cluster .

FAT32 The disadvantage of this method is that it supports the maximum partition capacity ,FAT32 2TB The capacity of the largest partition is still today , but FAT32 Only the maximum... Can be stored 4GB A single file of , therefore FAT32 Unable to store disc ISO Mirror image 、 HD video 、 All kinds of graphic works, files and so on , This is its fatal drawback .

U disc NTFS Format

NTFS file system NTFS(New Technology File System) yes Windows NT Core and advanced The server File system in network operating system environment .NTFS Our goal is to provide more than FAT32 Higher reliability , And eliminate FAT Limitations in the file system .NTFS In addition to supporting larger partitions 、 Larger files 、 Save more hard disk space , It also provides FAT Many functions that the file system can't imagine .

There are mainly ： Long filename 、 Compress partitions 、 Event tracking 、 Document indexing 、 High fault tolerance 、 Data protection and recovery 、 Encrypted access ……NTFS Support is greater than 4GB Due to NTFS Partition has become the absolute mainstream format of computer disk ,XP、vista、Win7 By default, the partition is formatted as NTFS System , So about NTFS It is necessary to emphasize the advantages and characteristics of , so to speak NTFS Is the best disk file system available , What is it for? U Disks and various memory cards are rarely used NTFS File system ? Let's talk about it on the official website of the computer store NTFS Defects in flash memory .

NTFS Although there are many advantages , But these are designed for the traditional mechanical hard disk , For the new Flash Flash memory materials may not be suitable .NTFS Partition is using “ Journal style ” File system , Because you want to record the detailed read and write operations of the disk , Yes U This kind of flash storage media will cause a greater burden , For example, access a file or directory as well , stay NTFS The number of reads and writes on the system will be more than FAT32 Come more , Theoretically NTFS Format U The disk is easy to damage , and 400MB The following partitions are also better than FAT16 It's a waste of space .

NTFS These additional features are no matter for SSD Hard disk and U Disks can cause different degrees of damage , So the new generation Windows 7 The operating system is specifically designed for SSD To optimize , Reduce the number of reads and writes and the generation of fragments by various means . And for U In terms of the disk , In itself USB The bandwidth is limited ,NTFS Frequent reading and writing of the file system occupying the channel will degrade the disk performance , For this reason, Microsoft has specially developed for mobile storage devices ExFAT file system .
