Yup. This. Now that I have 32 GB of RAM in my FreeNAS box I decided I really didn't need dedupe after all. I just don't have that much duplicated data, and I've got 60 TB of HDDs in the box. So I use the RAM for VMs instead!

Yeah dedup is mostly useful for massively multiusers setups, say mail, file sharing, etc etc. For small setups you can do a `fdupes` pass once a day and fix it yourself I suppose.
