Actually the opposite. The facebook hardware is built at scale on nearly the cheapest it can be. That said, they have a different fail scale than personal hardware.. they are ok if entire racks or areas in a DC blow themselves up because the data is spread out. That is different from a laptop where the failure means loss of everything since the last backup (aka never). So what is stored on the systems is a different usecase and how it is considered safe is different. That said they have probably put in a lot more on scale testing of the filesystem than Fedora could do.
