Ask HN: Best DB for power outages?

On a regular PC suggests you might be using consumer disks which may not be 100% reliable about committing transactions it is hard to know. You should probably test first. Some SSDs hve enough capacitors to commit in flight commands on power failure.

Any ACID database will work. Make sure your app uses transactions properly.
