Phoronix: Linux 3.18 File-System Performance Minimally Changed But Possible Regressions

With the Linux 3.18 development settling down, here's our usual benchmarks of the new kernel when comparing the file-system performance against the previous stable version (Linux 3.17) for EXT4, F2FS, XFS, and Btrfs.

I am still wondering when I should make the switch to XFS (from EXT4) in my hdd disk.
Has someone done it and feels it better now?

Switched over to XFS a few weeks ago and it's been running fine so far. I haven't had any experiences with corruption or anything serious yet though. As you can see from the benchmarks, the performance is roughly the same between the two filesystems.

I can say that I noticed XFS fragments much more than EXT4 in my experience and XFS's defragmenter leaves a lot to be desired.
IMHO, it's not worth switching to XFS from EXT4 or vice versa if you're already familiar with one.

Not critically, imho.

I used XFS for my movie collection on 2 Tb HDD. When the HDD died, I bought a new HDD with similar characteristics and formatted it to Ext4. No difference in performance.
