You can find out how fast the motors can potentially turn by just hooking one straight to your power source. I've found that some motor driver devices can't deliver as much current to the motors as they want to draw in order to go full speed.
Also many things sold as a 'motor' are actually what I call a gear motor. Inside the casing there is the actual motor which turns at relatively high speed, and then a set of reduction gears attached to the motor shaft that drive the output shaft that protrudes from the casing at a much lower speed (but much higher torque). All the servo motors I've seen, for example, are made this way and all the ones used to turn wheels as well. The speed of the output shaft depends on the voltage, the current, and the ratios of the reduction gears.
