Users running a Linux system hardly pay attention to the underlying filesystem. In fact, during the installation of Linux, there’s a tendency to often go with the default filesystem listed without exploring other available options. For windows, things are a lot easier since NTFS is the dominant filesystem. With Linux, there are numerous filesystems at your disposal. These include the Ext4, XFS, ZFS, and BTRFS.

The most widely used filesystems are Ext4 and XFS, with the latter being the default filesystem in RHEL-based distros and Ext4 being the standard filesystem in Debian and Ubuntu distributions. When choosing a filesystem some of the factors that need to be considered include scalability, stability, and data integrity.

In this guide, we will focus on Ext4 and XFS filesystems and seek to understand the differences between these two.
