SSD Cached basically most of your content are stored in hard drive but the portion of data that used very frequently like for example operating system file stored on ssd so much frequent used files will be much faster to access

Pure SSD is 100% of your data is stored on the SSD that mean all your files are fast to access . i really dont know why server still using SAN . 10k RPM hard drive isnt really that fast anyway . you better just buy ssd for less price than overpriced 10kRPM hard drive . even consumer grade solid state drive is much much faster than server grade hard drive that have 10kRPM in it . reliability?? well solid state drive is sollid and no moving part and that mean more reliability . so in 2017 there are no reason for that overpiced drive

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


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.

well if you dont want to get suspended you can try using IOPS limiter and also CPU Usage limiter because some vps provider doesnt allow 100% cpu all time .
