Linux Filesystems Overview — Not Only EXT Exists!

Created for the Hack Tools Dark Community

Ever wondered what other Linux filesystems are out there besides the good ol’ `ext4`? Here's a quick dive into the main ones you’ll come across in the wild.

---

Ext2, Ext3, Ext4 (Extended Filesystem)
Standard for most distros, evolved from the original `ext` for Minix.

Ext2: No journaling, but reliable and still in use on flash drives.
Ext3: Introduces journaling for better recovery and consistency.
Ext4: Supports huge files, more subdirectories, and is backwards-compatible (you can mount ext2/ext3 as ext4, but not the other way around).

Still the go-to for general-purpose use, especially `/` root partitions.

JFS (Journaled File System)
Created by IBM for high-performance multiprocessor systems.

Very lightweight on CPU usage
Fast recovery after power loss
Stable and suitable for servers with high reliability demands.

---

ReiserFS
By Namesys — designed as a drop-in ext3 alternative.

Known for speed, especially with small files.
Can be used on `/` like ext4.

for a deeper dive.

Development has slowed, so use with caution in production.

Btrfs (B-tree FS)
Oracle’s advanced, next-gen filesystem.

Features:
Snapshots and subvolumes
Built-in RAID
Transparent compression
Self-healing and checksumming

Default in OpenSUSE, great for complex storage setups.

---

XFS
Built by SGI, now lives in Red Hat-based distros.

Optimized for large files and big disks
Supports up to 2TB file sizes
Excellent performance for high-throughput workloads
Used by default in RHEL/CentOS.

Conclusion:
While `ext4` is a solid default, other filesystems have unique strengths depending on your use case — be it snapshots, compression, recovery, or high-performance I/O.
