Several commonly used file systems in Linux environment

1, ext2

ext2 is an scalable, high-performance file system designed to solve the shortcomings of the ext file system. It is also called a secondary extended file system. It is the most used type of Linux file system and is more prominent in speed and CPU utilization. ext2 has excellent file access performance and can support 256-byte long file names. It is a standard file system in GNU/Linux systems.

2, ext3

ext3 is the log version of the ext2 file system. It adds the log function to the ext2 file system. ext3 provides three log modes: journal, ordered and writeback. Compared with ext2, ext3 provides better security and upward and downward compatibility. Therefore, in a Linux system, an ext3 file system can be mounted instead of an ext2 file system. The ext3 file system format is widely used in current Linux systems. The disadvantage of ext3 is that it lacks the high-speed data processing and decompression performance of modern file systems. In addition, disk quota issues need to be considered when using the ext3 file system.

3. reiserFS

reiserFS is one of the most stable log file systems in the Linux environment. It uses a fast balanced binary tree algorithm to find the log files on the disk. The search speed of free space and existing files is higher than that of ext2. ReiserFS can dynamically allocate index sections like most other file systems without creating fixed index sections in the file system. Helps the file system to adapt to various storage needs more flexibly.

4, VFAT

VFAT is a file name system mainly used to handle long files. It runs in protected mode and uses VCACHE for caching, and has and Compatible features between Windows series file systems and Linux file systems. Therefore VFAT can be used as a partition for Windows and Linux swap files.
