BTRFS vs. EXT4: Difference and Comparison
By Muazma Batool & Muneeza Rehman — Published on May 31, 2024
BTRFS offers advanced features like snapshotting and dynamic inode allocation, while EXT4 provides stable and robust performance with broader compatibility.
Difference Between BTRFS and EXT4
BTRFS supports snapshotting and subvolumes, which are useful for backup and system recovery scenarios, whereas EXT4 lacks native support for these features, focusing instead on traditional file system stability and performance.

BTRFS features dynamic inode allocation, allowing the file system to expand the number of inodes as needed, while EXT4 uses a fixed number of inodes established at the creation of the filesystem, which can limit flexibility.

BTRFS includes built-in data integrity features, such as checksums for data and metadata, enhancing protection against data corruption; on the other hand, EXT4 provides optional data checksums but relies more on its journaling capabilities to ensure data integrity.

BTRFS is designed to manage large data volumes and complex storage environments with features like built-in RAID, whereas EXT4 handles smaller-scale storage more efficiently without built-in RAID functionality. BTRFS allows for online resizing (both expansion and reduction) of file systems, providing greater flexibility in managing storage resources; meanwhile, EXT4 supports only online expansion and requires offline intervention for file system reduction.
