Does ext4 need to be defragmented?

How do I defrag my ext4 partition?
If you have an ext4 file system created with the extent option (it’s the default in most recent distros), you can check fragmentation on it with e4defrag -c /path/to/check , and defragment it without umounting with e4defrag /path/to/check . But if you have enough free space you won’t need to do so.
Why does ext4 not get fragmented?
One way in which the ext4 file system keeps fragmentation in-check, is with the process of delayed allocation (ext4’s default allocation mode). Delayed allocation works by deferring the mapping of newly-written file data blocks to disk blocks in the filesystem until writeback time.
Does Linux need to be defragmented?
Although Linux file systems don’t need defragmentation as much or as often as their Windows counterparts, there’s still a possibility that fragmentation may occur. It could happen if the hard drive is too small for the file system to leave enough space between the files.
