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've been using a "high endurance" card. These are the only ones SanDisk will do their guarantee for if you use them in a Pi.

I’m using SanDisk Extreme Pro cards in my various Pis for years now. The worst that happened once or maybe twice in the past 10 years is a card going read-only. Which is easily fixed by cloning it to a new one and running fsck.
