Clarification on the deduplication section: ZFS doesn't automatically hardlink files (at least not in the sense you'll ever see a link count increase on your files), instead it checksums blocks and if two blocks are identical, it'll point both references to the same on-disk block. It might sound like a small difference, but it does keep the files independent on the VFS layer. You can modify a file without fear of unwantingly modifying other files at the same time, which would happen if they were hard linked.
