1. A management method for an address space of a low delay file system, comprising implementation steps:
1) generating a superblock and a block group allocation table by the address space of a storage device, wherein the superblock stores an allocation condition regarding file system information and blocks on the linear address space of the storage device, and the block group allocation table is configured to mark an allocation condition regarding data blocks in a corresponding block group; and
2) dynamically establishing or selecting the corresponding block group and allocating the data block according to an appointed data block size when a file is established, and writing file data into the allocated data block and updating information of the block group allocation table and the superblock.
