[Ubuntu Disk Format] Which File System Is Best for Ubuntu?

Knowing the file system to use is critical when starting with Ubuntu. It helps manage your files and data and drives out optimal performance from your computer. In this section, we'll discuss five file systems that are best for Ubuntu. Among these, you can choose your favorite based on preference.

1. Ext4

Extended File System 4 (Ext4) is the primary file system for Ubuntu. If you're new to Ubuntu and want a file system that you can easily get started with, Ext4 is best for you. Compared to its predecessors, Ext4 is an improved version. It allows you to incorporate bigger volumes and has an improved defragmentation system. You may also use EaseUS Partition Master Linux to know how you can easily format/partition Ext4 on Ubuntu.  

A feature that makes Ext4 stand out is its improved reading ability and load time. Therefore, it would be best if you went for it because of these features.  

2. BtrFS

B-tree File System (BtrFS) is excellent for reading and writing a pool of files and databases. This file system is superior to Ext4 due to its adaptability in the long run. It supports unique features, including:

  • Enhanced snapshot capability
  • Drive pooling
  • Defragmentation via online networks

Another factor that makes BtrFS the best file system on Ubuntu is that it can work well on large drive space. This is unlike the Ext4 file system. Despite being termed an unstable file system, BtrFS is still undergoing updates and improvements; hence you need to consider it a default choice.

3. ReiserFS

ReiserFS is a great alternative to Ext4. Like Ext4, it's stable and provides improved features than earlier Ext versions. Additionally, ReiserFS has an efficient storage management system than older file systems. The only disadvantage with ReiserFS is that its developers no longer provide updates. 

4. XFS

XFS is another file system that is best on Ubuntu. It has a few similarities with Ext4. These include delayed allocation and reduced fragmentation. A major drawback with XFS is that it doesn't work well for smaller files. However, compared to other file systems, it's the most suitable for larger files.  

5. ZFS

Sun Microsystems is the company responsible for developing ZFS. Unlike other file systems, ZFS comes with a volume manager integration. It's considered an improvement for BtrFS. Its features include enhanced volume management, snapshots, and drive pooling. ZFS allows you to easily recover from a drive failure, thanks to its advanced Raid-Z feature.

People use this file system by default to manage containers in Ubuntu.

Ubuntu's five best file systems include Ext4, BtrFS, ReiserFS, XFS, and ZFS. Ext4 is the best to get started on Ubuntu because it has improved reading ability and load time. If you want a file system that supports large drives, you should consider BtrFS. ReiserFS is a great alternative to Ext4 because it's stable and provides improved features.

XFS is another great alternative though it doesn't support smaller files. On the other hand, the ZFS file system stands out because of its volume manager integration feature. To format a disk on Ubuntu, you can 1) perform a quick format or 2) a detailed format using GParted.

GParted is always a great alternative if the quick format fails to work as expected. Although it has detailed steps, using GParted is a sure way to format your disk on Ubuntu.
