Default Gigabit Switch plugged into 10/100 Router

This is a basic networking question and something that I struggle with.

Say I have a switch with a number of Gigabit Ethernet ports on them and the switch is plugged into a Fast Ethernet port on a router.

If I connect my PC to one Gigabit port on the switch and my NAS to another Gigabit port on the same switch (in order to transfer large files from the PC to the NAS), does the traffic go through the router and, therefore, is the Fast Ethernet port on the router throttling the Gigabit ports on the switch so that they only operate at 100Mbps max?

Or does the traffic go directly between the Gigabit ports (at 1000Mbps) and bypass the Fast Ethernet port on the router?

I'm thinking the former, but a categorical answer would be appreciated.

Cheers.
