Which raid level do you need for a Minecraft server?

I want to know what raid level you need to run a Minecraft server! Also with server configurations

RAID has nothing to do with Minecraft servers. RAID is used (among other things) to ensure hard disk integrity. In other words, RAID ensures that the data on your system is not lost if one (or more) hard drives fail.

Game servers require more CPU and RAM. And you can't answer that here, too little details (how many players, "pure" Minecraft or any modifications…).

Okay thanks! I thought you needed a certain RAID level for application servers or something like that.
