EXT4 add more features;

  • Volumes up to 1 exbibyte (EiB).
  • Files up to 16 tebibytes (TiB).
  • Extents, improvement of large file performance and reduction of fragmentation.
  • Journal checksumming.
Just to name a few of them, check out wikipedia’s write ups for some pretty good explanations of the EXT.x file systems.
Next we will be getting in to the FAT family of file systems.
