the main reason for using dynamic NAT is that usually you have only a limited range of IP addresses available in a pool. Dynamic NAT entries time out and are only created when needed, that is, when there is traffic, while static NAT addresses do not time out, and remain in the translation table, regardless of wether there is traffic or not.
Here is what CCO says:
With dynamic NAT, translations do not exist in the NAT table until the router receives traffic that requires translation. Dynamic translations have a timeout period after which they are purged from the translation table.
With static NAT, translations exist in the NAT translation table as soon as you configure static NAT command(s), and they remain in the translation table until you delete the static NAT command(s).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
