Filesystems: The Digital DNA of Data Storage
Explore Linux filesystems through interactive visuals. Learn VFS, compare ext4 vs Btrfs vs ZFS, and understand file operations.
Explore machine learning concepts related to storage. Clear explanations and practical insights.
Explore Linux filesystems through interactive visuals. Learn VFS, compare ext4 vs Btrfs vs ZFS, and understand file operations.
Learn how filesystem journaling prevents data loss during crashes. Explore write-ahead logging and recovery in ext4 and XFS.
Understand Linux inodes - the metadata structures behind every file. Learn about hard links, soft links, and inode limits.
Understand Copy-on-Write (CoW) in Btrfs and ZFS. Learn how CoW enables instant snapshots, atomic writes, and data integrity.
Explore ext4, the default Linux filesystem with journaling, extents, and proven reliability. Learn how ext4 protects your data.
NTFS internals from the Master File Table outward: 1 KB attribute records, resident vs non-resident $DATA, run lists, alternate data streams, the $LogFile journal, and why dual-boot Linux distros prefer ntfs3 over ntfs-3g.
Learn the Btrfs filesystem with built-in snapshots, RAID, and compression. Explore copy-on-write, subvolumes, and self-healing on Linux.
Master ZFS filesystem with pooled storage, RAID-Z, snapshots, and checksums. Learn enterprise-grade data integrity on Linux.
XFS internals end-to-end: allocation groups for lock-free parallel metadata, B+ trees instead of bitmaps, extent-based allocation that scales to terabytes, and delayed allocation that turns scattered writes into contiguous extents.
Learn FAT32 and exFAT filesystems for cross-platform USB drives and SD cards. Understand file size limits and compatibility.
RAID storage visualized: RAID 0, 1, 5, 6, and 10 levels explained. Learn how they work, when to use them, and disk failure recovery.
