| Apr 14 at 19:54 | comment | added | Atomic Tripod | "Ext4 doesn't need defragmentation" is an oversimplification. I observed 17% fragmentation in OpenMediaVault in a large file NAS (30+ GB per file). It seems to depend on the design of the OS and its use of ext4 rather than a blanket "never defragment". I can't say whether it significantly affects performance. | |

Related question on Ask Ubuntu: Why is defragmentation unnecessary?, where the current accepted answer is: The underlying filesystems used by Ubuntu, like ext2 and ext3, simply don't need defragmenting because they don't fragment files in the same way as NTFS. There are more details athttp://en.wikipedia.org/wiki/Ext3#Defragmentation.

| Jan 15, 2013 at 21:39 | comment | added | nerdwaller | If you are as interested as you sound, perhaps this paper would be of interest regarding this: Fedora Project, specifically starting at page 179 (which is really page 3) | |
