Reply to comment by wmantly in TIL that flight recorders must be able to withstand an acceleration of 3400 g for 6.5 milliseconds and that this is roughly equivalent to an impact velocity of 270 knots (310 mph; 500 km/h). by IchBinKoloss

The rest of the plane acts like a crumple zone, slowing down the recorder before it suddenly stops.

In a breakup it would hit the ground at terminal for the chunk it's a part of, which would be much less aerodynamic than the whole aircraft.
