I REALLY want to try mongo for a side project I am building, however the single server durability is an issue. My data could easily fit in mysql/postgres however I am storing data that fits better in a document store. I am inclined to just use postgres for now because it's sort of silly to set up/pay for multiple servers for such a small project.
UPDATE: Apparently my information is out of date. Hopefully my confusion (and the answers below) helps someone else. Thanks.
