In hard drive memory, as in life, nothing lasts forever - not even solid state drives. This article is interesting not only because it described how the solid state drives fail ("... the back-and-forth traffic erodes the physical structure of the cell, leading to breaches that can render it useless. Electrons also get stuck in the cell wall...") it also tells us how much use you'll get from them before they die. The answer? A lot! "Errors didn't strike the Samsung 840 Series until after 300TB of writes, and it took over 700TB to induce the first failures. The fact that the 840 Pro exceeded 2.4PB is nothing short of amazing, even if that achievement is also kind of academic."
