Low poly game model of HDD, only 1 mesh and 1 material, textures in PBR (base color/metal/roughness), normal in opengl format (green channel is not flipped)
I also attached some additional textures that were made at the stage of baking from a high-poly model (normal (opengl), ao, curvature, matid, thickness) so you can use them to create your own textures or to use them in specific shaders in the game engine
size of all textures: 1024x2048
