Windows 8 Storage Spaces allows the user to define some data to be stored with high redundancy (2-way, 3-way) and some data with less redundancy (RAID5 equivalent). Is this somehow possible with ZFS? it's a killer feature for home users, since most of the data don't require mirror-safety (films, music) and some other would benefit from even a 3-way mirror. At least, I would like it a lot.
Is this possible by using different datasets within the same pool? I don't think so, but I ask
