> I'd love to switch to ZFS, but the RAM requirements are absurd. I don't have a separate storage server, and I'm not really to sacrifice 10GB of RAM (1GB/TB of storage if I'm to believe what I find through Google) on my home desktop just for it when the vast majority of my data could probably handle a rotted bit or two.

Please explain where this number comes from. I run ZFS on boxes with as little as 4GB of RAM, which are also doing all sorts of other things in addition to ZFS.

As with all filesystems on Linux, more RAM means more cache, and if you have free RAM you will benefit from a dynamically resized filesystem cache. That RAM is however not required and the cache can be evicted under memory pressure.

Its the recommemded setup if you want to use dedupe, aside from that it doesn't really meed more ram than any other fs.
