Sorry Lasse, but where did you read that you have to disable those services? Is this a measure to extend the operational life of your SSD?
If you defrag your ssd you will reduce its lifetime and sometimes make your ssd more fragmented because ssd have wear leveling. So do not defrag your ssd. Disable any prefetch - this will make the lifetime a little bit better and your applications still loads fast (if you have a okay ssd, not JMicron).
