Techopedia Explains Superblock

The superblock essentially records a file system’s characteristics – block size, other block properties, sizes of block groups and location of inode tables. The superblock is especially useful in UNIX and similar operating systems where a root directory contains a variety of subdirectories. The inode stores other file metadata, excluding its name and actual contents.
