What kind of hard disk partition format Linux uses is better

The personal comparison recommends ReiserFS, the speed is fast, the effective space is big, ext3 also can, but the relative waste hard disk space. In addition, there are JFS, XFS and so on. Ext2 is not recommended, because there is no log file, accidental power loss will not be able to recover data.

The following are a brief description of each partition:

ReiserFS is a new type of file system that accommodates data, including file data, file names, and log support, in a different way-a completely balanced tree structure. ReiserFS also supports massive disks and http://www.aliyun.com/zixun/aggregation/20901.html "> disk arrays, and can continue to secure fast search speed and high efficiency.

EXT3 is a log-file system that is an extension of the ext2 system, compatible with ext2. The advantage of the log-file system is that because the file system has a cache layer involved, you must remove the file system if you do not use it to write the cache data back to disk. Therefore, every time the system shuts down, all its file systems must be shutdown to be shut down. If the file system has not been shutdown before the shutdown, such as (power failure), the next reboot will result in file system data inconsistency, it is necessary to do the reorganization of the file system, will be inconsistent with the wrong place to repair. However, this re-engineering effort is time-consuming, especially with a large capacity document system, and it is not guaranteed that all information will be lost.

JFS A byte level log file system, using the technology of database protection system to record the change of files in the form of log. JFS guarantees the integrity of the data by documenting the structure of the file rather than the changes in the data itself. This approach ensures that the accessibility of the data is maintained at all times. XFS is a 64-bit file system that can support millions of T-byte storage space. Support for oversize files and small size files is outstanding and supports a large number of catalogs. The maximum supported file size is 263 = 9 x 1018 = 9 Exabytes, the maximum file system size is exabytes. XFS uses a high table structure (b + tree), which ensures that the file system can be quickly searched and quickly allocated to space. XFS continues to provide high-speed operations, and file system performance is not limited by the number of directories and files in the directory.

EXT2 is a standard file system in the GNU system, characterized by excellent access to file performance, for small and medium-sized documents show advantages, which mainly benefit from its cluster of high quality design. Its single file size and file system itself is the upper limit of the file system itself and the size of the filesystem itself, in the common x86 computer system, the maximum number of clusters of 4KB, the single file size of the upper limit of 2048GB, and file system capacity of 16384GB. However, because the core 2.4 can use a single partition maximum of only 2048GB, actually can use the file system capacity is only 2048GB. As for the Ext3 file system, it belongs to a log file system and is an extension of the ext2 system. It is compatible with ext2, and converting from ext2 to ext3 is not complicated.
