Unexpectedly, the next version of Fedora uses the Ext4 File System by default. Fedora 11 is expected to be released by the end of May.

Another major release of Ubuntu 9.04 is expected to still use Ext3 by default, and Ext4 will be used as the installation option.

Many comments in the LWN article have praised the advantages of Ext4. The Phoronix test also shows that Ext4 is indeed faster in many aspects than ext3. Ext4 provides many new features for desktop users, including faster file system checks, efficient storage of large files and reduction of fragments, multi-block allocation (faster writing ), delayed block allocation, log verification, and so on. As a tradition of the extfs series, the current ext3 file system setting to ext4 can work seamlessly, but in the same disk format, most new features will be unavailable. Therefore, the new ext4 format or the conversion of ext3 to ext4 can provide the best experience.
