I'm a little worried that at some point DCS will end up using more than one 500GB SSD. I hope the rapidly rising demand for storage is something that's on the radar for Eagle Dynamics.
I completely understand that high quality textures and models take up a lot of space, but I find that the maps especially tend to take up a lot more space than they should given the level of fidelity. There are other flight sims with more detailed terrain that don't use nearly the same amount of space.
I realize that fixing this sort of thing can be a seriously huge operation, possibly dealing with the engine, but at some point the storage requirements are going to become a serious problem. Given that we're all asking for more maps, I'm a little worried about what it's going to mean, because DCS already take up half of an SSD for me.
