Switching from Raspberry Pi 4 to Home Assistant Green or Yellow? (lemmy.world)

I've been using the same Raspberry Pi 4 to host HA for years. It's worked well enough, but I worry about the stability of the SD card. I'm no stranger to cards that fail suddenly. Had one fail on another Pi just yesterday.

The various HA hardware offerings (Green/Yellow) use more stable flash storage. Can I swap out one hub for another? If so, how difficult is it? What would I be gaining or giving up by going with HA's offering? I know the Yellow has a built-in zigbee radio and PoE, but you need to buy a Pi compute module. There are also fewer USB ports on both the yellow and the green compared to the pi.

I know I could use any computer to host HA, and thus gain arbitrarily performant storage/memory/other stuff. Is there any advantage to, say, having more storage? What exactly is HA storing besides the history of entity states?

I used a pi for HA for years with no issue. Just use a good quality legitimate sd card and make regular backups of your setup

I use a cheap NUC now but that is about processing overhead mainly due to rtsp streams. If you have a setup like mine (10+ cameras, 4k streams) you’ll find it starts to get unusable and chokes after a certain number of streams (iirc like 5-6). This is exacerbated if you bridge the streams to homekit or stuff like that (though not as much if you do something like scrypted external to the pi obviously but then it’s like what do you run that on?)
