Linux
1, Linux: the presence of dozens of types of file systems: ext2, ext3, ext4, xfs, brtfs, zfs (man 5 fs can get all of the file system presentation)
Different file systems use different methods to manage the disk space, advantages and disadvantages; are specific to the file system partition, so the format for the partition, the partition format refers to the use of the specified file system type registration partition space, and to establish the corresponding index table management process.
- ext2 with great speed and minimal CPU utilization, may be used for hard disks and removable storage devices
- ext3 increase logging function, backtracking
- ext4日志式文件系统, support 1EB (1024 * 1024TB), the largest single file 16TB, support sequential writes can reduce file fragmentation. rhel6 default file system
- xfs can manage the 500T hard drive. rhel7 default file system
- brtfs file system optimized for SSDs do,
- zfs update?
Note: EXT (Extended file system) is an extension of the file system, extended file system, ext1 published in April 1992, it is the first file system for the linux kernel does.
Formatting commands: mkfs -t <file system type> <partition device file name>
mkfs.xfs /dev/sdb1
man 5 fs can get a brief description of all of the file system
Maximum support files and other information?
windows
- FAT16: MS-DOS format and partition disk win95 employed, the 16-bit file allocation table, supports only 2GB of disk partitions, 2GB largest single file, and the disk utilization is low
- The FAT32: (i.e. Vfat) uses 32-bit file allocation table, maximum support partition 128GB, maximum file 4GB
- NTFS: supports a maximum partition 2TB, the maximum file 2TB, security and stability is very good, less prone to file fragmentation.
other
- RAMFS: memory file system
- ISO 9660: CD
- NFS: Network File System
- SMBAFS / CIFS: Samba supports Network File System protocol
- Linux swap: swap partition to provide virtual memory.
