I recently rebuilt my NAS and took the opportunity to redesign based on some of the ideas from PMS. ZFS needs to lookup 1 random sector per dedup block written, so with "only" 40 kIOP/s on the SSD, you limit the effective write speed to roughly 100 MB/s. 0, XFS is the default file system instead of ext4. Pro: supported by all distro's, commercial and not, and based on ext3, so it's widely tested, stable and proven. But they come with the smallest set of features compared to newer filesystems.
