Take a look at the documentation for Journaling: http://www.mongodb.org/display/DOCS/Journaling
This covers what MongoDB is doing for durability.
Single server durability is a disk buffered list of pending writes so if the server reboots while in operation it can just resume where it left off. In larger deployments this risk is handled by having multiple servers running concurrently.
Does this sound right?
