Thanks for the answer. Can the durability of the fused quartz be compared to the durability of this storage format though? (from a more detailed article [1])

  Well, there are a couple of different questions here. One is about resilience to physical shocks such as falling and mechanical stress, which could destroy the disc but won't do anything to the nanogratings. The other is about gradual, continuous decay processes — over a sufficiently long period of time, random thermal fluctuations will destroy any solid object, and analogous but larger-scale relaxation processes will destroy galaxies as well. Such processes could cause the nanogratings to decay long before the fused quartz itself evaporates. The nanogratings do have a certain amount of built-in redundancy; they're holographic phenomena.
