I just want a huge volume to store it on. If some sort of redundancy can be built into that, that's very nice. I've been using GEOM (gconcat) so far, but I'd like to move to ZFS due to it's ease of use (apart from tuning your system to it) and also because GEOM is not able to provide any raid5-like setups.

I also read/noticed that ZFS seems to run best on AMD64 platforms. That's OK then.
