Ein merklicher Unterschied ist EXT4 Eingang (seitlich) 4-polig S-video (32/37WL). 3 Unterstützte Formatierung: FAT16/FAT32 (lesen-schreiben), EXT2/EXT3 (lesen-schreiben), NTFS (lesen-schreiben), MAC OS / HFS+ journaled (lesen-schreiben), ExFAT. 4 Ext2, Ext3, and Ext4 are all extended file systems created for Linux. But they have differences in many aspects like file size limit, default inode size, journaling, and so on. Now, we will explore the differences of Ext4 vs Ext3 vs Ext 2 in detail. 5 Ext4 is the default file system on most Linux distributions for a reason. It’s an improved version of the older Ext3 file system. It’s not the most cutting-edge file system, but that’s good: It means Ext4 is rock-solid and stable. In the future, Linux distributions will gradually shift towards BtrFS. 6 The ext4 file system supports backward compatibility with ext3 and ext2 file systems. An additional feature is the automatic mounting of the ext3 file system in ext3 mode by using an ext4 driver. Allocation Improvements. The ext4 file system allocates storage blocks more efficiently prior to writing them to the disk. 7 Ext2 and Ext3 use e2fsporgs as a standard utility. It makes the conversation between both the file systems easier and smooth. Ext3 is designed with new features such as journal, online file system growth, and HTree indexing large directories. Ext3 used less CPU power as compared to other Linux file systems. 8 File system repair time (fsck) in Ext4 is much faster than in Ext2 and Ext3. Some file system repairs have demonstrated up to a six-fold increase in performance. Currently, Red Hat’s maximum supported size for Ext4 is 16TB in both Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6, and 50TB in Red Hat Enterprise Linux 7. 9 The ext2, ext3, and ext4 file systems are a family of file systems that have a strong amount of backwards and forward compatibility. In fact, they can be considered a single filesytem format with a number of feature extensions, and ext2, ext3, and ext4 are merely the names of the implementations found in the Linux kernel. 10 Unterstützte Formatierung: FAT16/FAT32 (lesen-schreiben), EXT2/EXT3 (lesen-schreiben), NTFS (lesen-schreiben), MAC OS / HFS+ journaled (lesen-schreiben). 11 12
