Choosing the right Linux filesystem can make or break your Linux system performance and data safety. In this guide, we compare EXT4, Btrfs, ZFS, XFS, F2FS, and Bcachefs to help you decide which one to use.

You'll learn:
✅ How each filesystem works under the hood
✅ The pros and cons of every option
✅ Which filesystem is best for your specific hardware (SSD, HDD, NVMe)
✅ Snapshots, RAID, and data integrity features explained
✅ Why Btrfs and ZFS are game-changers for data protection

Whether you're setting up a new Linux install, building a NAS, or just curious about how filesystems work, this video gives you everything you need to make an informed decision.

This video covers Linux filesystem comparison including EXT4 vs Btrfs vs ZFS vs XFS vs F2FS performance, snapshots, RAID, and data integrity features.

A comprehensive comparison of five Linux filesystems: Btrfs, ext4, XFS, F2FS, and ZFS. Btrfs is recommended for most desktop users due to its snapshots, transparent compression (zstd), and subvolume layout. ext4 is the battle-tested, simple choice for older hardware or users who want no complexity. XFS excels at large-file and high-throughput workloads but cannot be shrunk. F2FS is purpose-built for NAND flash longevity, ideal for USB drives and SD cards. ZFS offers enterprise-grade pooled storage, RAID-Z, and ARC caching but requires significant RAM and carries licensing complexity on Linux. A decision tree helps readers choose based on their priorities: features, speed, simplicity, flash longevity, or multi-drive setups. BcacheFS is mentioned as experimental and not yet production-ready.
