When you have 9.x, corral, 11.x etc, all with different bugs and quirks, with not a lot of documentation, I feel I could not recommend IX products. I know many users with similar experience. I love BSD, there are some of us that feel that freenas has gotten to large, which is why the corral fiasco was able to happen. Ive set up probably hundreds of freenas instances, ive done my homework. I just want the ability to freebsd-update fetch 11.x.x and update jails as I see fit. Nas4free seems to allow for a more complete jail system. Also for a new user, sure they can do homework, but you have 2 GUI’s, multiple stable channels (9, 11) a whole lot of options, I feel like its an advanced solution, trying to go mainstream. So Id also say that plugins are a bit weird, they are hardly ever updated (security risk) and it makes more sense to use jails. For a NAS, simple is always better for the end user who may not know what ZFS is but just wants a backup system. Just all my opinion as a long time freenas enthusiast
Edit: My apologies, I do not mean to offend, just my opinion, I love discussing this because there are 2 sides to everything.
Edit 2: I did look into unRaid a while back but I did not need something like that, though you could run docker and use that for “jails”. Nas4free does storage really well, I mean its a fork of freenas. I just think freenas has gotten to bloated for the development, which is why its a bit of a mess. Everyone knows that you do not use even a stable version of freenas until it has been out a while and had the “bugs” fixed. And since all I need in a nas is, well, a nas, nas4free might suit me better. So just an opinion supported by most of the people Ive discussed it with.
