$80? I run mine on a Pi Zero that I got for $9 with a $6 wired network adapter for a grand total of $15. No problems for a household of five with one of us (me) being an extremely heavy user.
I used to do that, but it comes with the problem of your DNS going down any time you want to restart or do a hardware swap on your NAS. Or since it was running in docker something as simple as reloading docker would knock out the internet for a few minutes. It's worth the $15 to have them operate separately.
Doesn't that just move the problem to the $15 device? Or are you saying you reboot your NAS significantly more often than your RPi? I have a RetroPie setup that I reboot about as often as my NAS, which is when I remember to run updates.
I pretty much never reboot the Pi. It currently has over 18 months of uptime on it. My NAS on the other hand I probably restart for one reason or another maybe once every 6 months. So yeah I'd say I reboot it minimum 3x more often.
Plus a reboot takes much longer on my NAS than on the Pi. The server board is slow to start, the SAS cards are slow to start, and unRAID is slow to start. Then I need to manually enter the password for disk encryption. Then wait for the array to start up. Then wait a bit more for the docker containers to start. Add all of that up and even the absolute fastest reboot is like 10 minutes while the Pi probably takes 30 seconds.
And what if I want to swap hard drives? Now it's down for an hour. I guess I could wait until 3am to do all my upgrades so everyone is asleep, but I'd rather not. I suppose if it were just for myself it would matter a lot less. But again, it's only $15 to not have to think about it at all.
Interesting. Boot times aren't an issue at all for me on my NAS because it's running on an old desktop processor and has plenty of performance. Both boot in <30s, and I leave them both on 24/7.
I tend to upgrade all my servers around the same time (RPi, NAS, VPS), and my laptop and desktop get updates about every week or two. I don't like leaving systems unpatched, so I stay on top of it. I haven't needed to swap HDDs in the 6-ish years I've had my NAS configured, so I guess it's not an issue I've run into. I'd probably just schedule it when I do a router firmware update (I run a Mikrotik router), which I do every few months as well, since that way everyone expects a little downtime.
