- Choose the block size (1024,2048,4096 byte)
- Partition disk blocks into group (lower average disk seek time)
- Preallocate disk data block to regular files.

Ext3 File System
- Ext3 is the new version of Ext2 and adds journaling mechanism, but the basic structures are the same
- Addition of an online file system
- File system journaling
