So yes, btrfs have more functionality. Some of them can be really great for OS drive (said it before). Allow rollback after an upgrade, snapshot per file and so on. But for the data... I don't need more functionality, I need something 100% stable, repairable on worst scénario, and wich make me feel secure. Because I can tell exactly how my files are stored, exactly where on the drives etc.
