[Discussion] What Is EXT4? - Let's Know Details

Hey Mi Fans,
How are you all? Did you ever see these words EXT4, F2FS, VFAT, Fat32, Exfat, EXT3, EXT2, NTFS? Well, these all are an individual file system. In computing, a file system is used to control how data is stored and retrieved. Without a file system, information placed in a storage area would be one large body of data with no way to tell where one piece of information stops and the next begins. By separating the data into individual pieces, and giving each piece a name, the information is easily separated and identified.

Taking its name from the way paper-based information systems are named, each group of data is called a "file". The structure and logic rules used to manage the groups of information and their names are called a "file system". Today In my this thread I'm going to let you know details about the EXT4 file system.

Ext4 is the evolution of the most used Linux filesystem, Ext3. In many ways, Ext4 is a deeper improvement over Ext3 than Ext3 was over Ext2. Ext3 was mostly about adding journaling to Ext2, but Ext4 modifies important data structures of the filesystem such as the ones destined to store the file data. The result is a filesystem with an improved design, better performance, reliability, and features.

Ext4 uses extents (as opposed to the traditional block mapping scheme used by ext2 and ext3), which improves performance when using large files and reduces metadata overhead for large files. In addition, ext4 also labels unallocated block groups and inode table sections accordingly, which allows them to be skipped during a file system check. This makes for quicker file system checks, which becomes more beneficial as the file system grows in size. The maximum file size limit of EXT4 is 16 Terabytes in a single file, 1 Exabyte in a single volume.

  • Doesn't suffer file size limitation of 4GB
  • Regarded as a very stable file system
  • Contains many features such as encryption (used in adaptive storage)
  • Supported in all modern smartphones (well supported)

  • If journaling is present (enabled by default), it can have a negative effect on the lifespan of your flash storage
  • EXT4 formatted external SD cards may have trouble mounting and some apps may not be able to work correctly

So, Mi fans I hope now you at least know something about the EXT4 file system. Maximum Smartphone comes with the EXT4 file system as it has the best stability. But you can shift to others, how? We will discuss it on later. Till then stay safe, be safe & keep an eye on Mi Community Bangladesh.
