Should I boot from ssd or from micro sd and run docker on ssd?

Configuration

I used a raspberry pi with micro SD and docker for a while on my Home Assistant. Unfortunately the SD started failing, probably due to the constant writes from HA.

I will move to an SSD, but I have a question:

Is it better to boot from a micro SD, then use docker with a volume from the SSD, or boot everything from the SSD directly?

Is there a difference in this case? The pi will not be constantly writing to the micro SD anymore, it will basically just read from there, and write everything to the SSD because it will be the docker volume.

The advantage of still using the micro SD for boot is just maintenance is easier, installation is easier as well

Forget the sd card and just boot from SSD. Why do you feel the need for docker?

Also bare in mind if running an SSD from a usb port you may run into power issues, especially if running some USB dongles as well.

Why NOT to buy a PI to run Home Assistant
