Helldivers 2 takes up around 150GB to install on PC (three times larger than on console), and the game's deputy technical director has now explained why that won't be changing anytime soon. As the older storage drives use a physical arm to read data, duplicating that data can make it quicker to find and thereby reduce loading times. SSDs don't work in this way, which explains why the console versions of Helldivers 2 take up less storage space. In the long term, engine improvements are planned to not waste RAM loading data that isn't needed. We are very carefully weighing up the costs and tradeoffs of the options we have, and we'll be sure to find a better balance between loading times and installation size soon."
