The server is amazing, way quieter than I expected, I had a whole soundproofed rack planned, but the fans just chill at 20%! I think it’ll be almost silent once I have the rack built.
Lots of people get on okay with it, and I’m not the most experienced, but docker problems with Scale seem to be common, and the direction TrueNAS is going with Scale isn’t going to make it any better.
I think Core is a bit better. But I’m definitely going to move away from it for Docker. Unraid was so easy for Docker, and I see it has ZFS support now, I’ll let you know how I get on.
Also, don’t forget the 720 has an internal USB port, because I did!
