Wow, 8TB, that's a lot of girly pictures! For the same general use purposes, do SSDs put out significantly less heat versus HDDs and also burn less electricity, and enough so to, for example, help eliminate the need for fans? For the typical consumer, not necessarily what to decide what to stuff into an HP 980, is it now clear that cost per byte is evening out and that soon the typical array of laptops in your local Best Buy including the cheaper of the lot will have SSDs? Tl;dr, are hard drives being completely phased out faster and faster?
