Is it normal to need to change both brake pads and rotors on a 2005 Volvo S40 with 30k miles?

I'll start by saying I am a volvo dealership tech. Volvo brakes wear quickly but work very well, It is a compramise, you either get long life out of your brakes with inferior stopping power or you can have softer faster wearing brake pads and rotors and have far superior braking power. It is by no means abnormal for your vehicle to need brake pads and rotors at 30k, If you have any doubt you simply ask the service advisor what the rotors currently measure and ask what is the specification that the rotor needs replaced, All rotors wear out over time and there is always a min. thickness specification at pad replacement, I do beleive your vehicles rotors need to be repaced when they measure around 23.8 mm.
