ZFS vs XFS

I’ve found XFS more well suited to extremely large filesystems with possibly many large files. I’ve had a functioning 3.6TB XFS filesystem for over 2 years now with no problems. Definately works better than ext3, etc at that size (especially when dealing with many large files and lots of I/O).

What you get with ZFS is device pooling, striping and other advanced features built into the filesystem itself. I can’t speak to specifics (I’ll let others comment), but from what I can tell, you’d want to use Solaris to get the most benefit here. It’s also unclear to me how much ZFS helps if you’re already using hardware RAID (as I am).
