In a Minecraft server, one of the strongest bottlenecks are disk I/O related operations (e.g. Why it makes sense for Minecraft servers Unfeasible if the world size exceeds the available RAM.Ramdisks are cleared when a system restarts (Not true for Dataram RAMDisk).Very low seek time (searching between and in files).Very high transfer speed (data to application).Many utilities however make it possible to backup Ramdisk data at set intervals, and before the system is shut down, then load the last data when the system starts up.

They offer significantly higher data transfer rates (between 3,000MB/s and 15,000MB/s) at the cost of volatility (data is lost after restarting the computer) and space (limited by the amount of RAM installed on the system, including swap space). Ramdisks are virtual file systems (unlike HDDs which are hardware) that live completely inside the computer's RAM. 4 Why it makes sense for Minecraft serversĬonventionally, files and directories are stored on hard disk drives which, by today's standards, offer a lot of space at mediocre data transfer rates (between 80MB/s and 200MB/s).
