There is actually quite a lot of relevant research available that can at least in principle answer that questions (although that research is of course always ignored in the public debate).
As far as I understand it is depends on the type crime. When it comes to "minor crimes" such as speeding we are deterred by the fact that we might get caught and punished.
For minor crimes there is indeed some correlation between deterrent and the severity of the punishment.
However, that correlation breaks down for serious crimes such as murder and rape. There is no research that shows any clear correlation between the "willingness" to commit a crime and the severity of the punishment once you pass a certain point; for the potential perpetrator it does not really matter if he/she would spend 10 or 50 years in prison if caught. This is probably partly because the risk of getting caught simply does not enter into the equation at all, either because it is not a planned crime or because the perpetrator believes that he/she will not get caught.
Another factor is that for for most people 10 years is already such a long time that it becomes quite abstract; you can't imagine being away even that long, nor who you would be when you get out.
