I see so do you have a minecraft server? because right now I'm studying to develop a ragnarok server, but is there any disadvantage with ssd-cached if it's use for game server?

I dont run minecraft servers on my VPSs because it might get suspended :3

For game servers ssd cached disks are enough. There is no reason to buy true SSD, it will not be significantly faster. And a HDD or a SSD cached disk is much cheaper.

Yes they are enough. Unless the game server uses a lot of IO that can lock up.
And as far as I know minecraft servers does a lot of IO for saving worlds.

Also of course, game servers that uses some kind of DB will be faster on SSD.

Game servers that use small flat-files for saving info should still be pretty fast on SSD-cached though.
