File Systems

Ext4 - The default file system

  • Improvements in file systems and sizes
    • File system size increased to one exabyte (1 EiB)
    • File size limit is sixteen terabytes (16 TiB)
    • No limit on number of sub-directories
  • Performance
    • Extents increase performance in certain situations, especially large files
    • Multiblock allocation is a new file block allocation method with faster write speed
    • These combine with delayed allocation of blocks for better performance and fragmentation
