^Bunneh: Why would we get enterprise google SSD's. That would be silly. RAMdisk (not the enterprise ones that attach onto PCIe slots) is considerably faster than any ssd on the planet.
To mattme1: What exactly are you trying to argue here? The entire map will take no more than 30-40gb total when the worlds are combined after the "new world" is made. We can easily store the core server in the ram, the entire world on the SSD, and fast hard drives for backups. The backups are rarely used, only in the case of damaged data.
