It is a constant topic of discussion. I see it come up at least once a week.
A USB stick is basically an SD card that plugs into a USB port. It has the same problems regarding multiple writes as an SD card does. To avoid corruption you need an external HD or SSD, or just run entirely in read only mode and use a RAM Disk for those things that must absolutely allow writing or else things don’t work.
Interesting. I’m in the process of replacing one of my Pis (original generation B) with a new Pi 3 for that very same reason. Hope I don’t have the same problem again with this one. I’ve added a bunch of new jobs for this little guy to do (running OH is not one of them though).
Finally, to add my two cents: I’m running OH (and a TON of other stuff) on an old but powerful laptop. This laptop isn’t powerful enough to virtualize my whole environment, but I am working towards Dockerizing everything so I can very quickly rebuild the machine should I have an outage or massive failure.
