The exceptional strength and energy absorbing design of the landing gear of the Blackhawk is another big plus when it comes to safety. It will accept 500 fpm;
It will do a bit better than that, Shy. The Black Hawk and Apache have demonstrated their ability to absorb hard landing impacts of up to 6.1 m/s (20 ft/s) with minimal or no damage to the aircraft and no injury to their occupants. That's 1200fpm.

The Black Hawk and Apache rely heavily on the fixed landing gear and seats to provide the required attenuation of loads for the 12.8 m/s (42 ft/s) design pulse. The landing gear alone were designed to handle over half of the total energy of a crash, with the floor and the seats absorbing the rest.

42fps is 2520fpm, which, IIRC, is the ROD of a Lynx in autorotation. Now that is impressive. In theory you could forget about the check/flare at the bottom and get out and walk away. In theory.
