The ext3 file system is essentially an enhanced version of the ext2 file system. What is it recommended for? Internally, XFS is organized in balanced B+Trees and uses Extends to store data. You can mount this partition and start writing and reading files like a hard disk partition. It doesn't support the set of file attributes that ext2 does (immutable, etc) 2. The simplest place to store a log is as an actual file within the filesystem to which you are logging changes. The majority of modern Linux distributions default to the ext4 filesystem, just as previous Linux distributions defaulted to ext3, ext2, and—if you go back far enough—ext. Advantages and disadvantages between NTFS, extfs2, and extfs3. Faster access speed. File systems are generally operating system dependent. If Apple and Microsoft have their own file system, GNU / Linux also has the systems ext2, ext3 and ext4 that are evolutions of the same system that only works natively in this operating system and not in Windows or macOS. XFS was ported to the Linux kernel in 2001; as of June 2014, XFS is supported by most Linux distributions, some of which use it as the default file system. thanks Nothing in life is is free and ext3 and journaled filesystems are no exception to the rule. tem implementation is about one eighth that of ext3 with similar functionality. The performance (speed) of ext3 is less attractive than competing Linux filesystems, such as ext4, JFS, ReiserFS and XFS.But ext3 has a significant advantage in that it allows in-place upgrades from ext2 without having to back up and restore data.
