Syno 920+ for me

Go build it and use unraid. Synology makes good products but they put a pretty big markup on it. Besides building it will give you a better understanding of its architecture.

Got a Xeon E5-2690v2 with TrueNAS Scale and a Synology DS418. Having used both pretty heavily over the years I can safely say I'm indifferent. The Synology is efficient; the TrueNAS Scale box performs really well with the added bonus of being able to run Kubernetes and Docker workloads. They're both sitting in their respective corners, doing their respective things, with minimal intervention.

I bought a used Datto NAS and put xpenology on it. Without drives, $300 got me 4 bays, 1 internal 2.5", dual 10gb nics, and 32gb of ecc ddr4. If you're ok using the hacked bootloader for synology's os, it's hard to beat.

I picked up an old Dell Optiplex tower and slapped 4 cheap 4 TB drives in it. Setup as RAID 5 I got 12 TB of "redundant" storage for cheap! Perfect spot to keep all the p0rn torrents.

But I used OpenMediaVault for that deployment. It's been OK.... but I kinda feel that I am missing out on some of the more active developments of other distributions.

Despite that, I would absolutely suggest grabbing an old office computer and throwing some drives into it for a home NAS.

Understand that this is a rabbit hole where you’ll hear a million opinions. If you’re just starting out, I’d recommend keeping it simple. It’s been a while since I looked at what’s new, but I’d look at truenas scale or unraid first.

I personally use truenas core (based on freebsd) but truenas scale (based on debian) opens up more options like docker that might be useful in the future.

I recommend sticking to hardware you already own until you run into something that you can’t do. Then you’ll have a better idea of what to look for and how everything works.
