    Every once in a while I hear of a crazy experimental storage media like this and get really excited. And than I never hear about it ever again. That's a shame.

      Same with batteries, usually because there's some massive deal breaker floating under the surface of the impressive claims. And there it is! Ouch. Really feel for the person tasked to make 230kb/s...

      Same with batteries, usually because there's some massive deal breaker floating under the surface of the impressive claims.

      The new approach can write at speeds of 1,000,000 voxels per second, which is equivalent to recording about 230 kilobytes of data (more than 100 pages of text) per second.

      And there it is! Ouch. Really feel for the person tasked to make 230kb/s sound impressive. It would take 68 years to fill that 500tb disc at those speeds, interestingly almost exactly a 32-bit Unix epoch.

        Same with cancer treatments, quantum computing, and nuclear fusion.

        Although honestly I do understand why that is, being a combination of hyperbolic click-hungry science journalism and the natural development processes requiring years or decades of further testing, incremental steps, etc.

          Yup. The sad thing is that the perpetually overhyped news articles overshadow the real progress being made in those fields, and the perpetual disappointment and unrealistically high expectations...

          Yup. The sad thing is that the perpetually overhyped news articles overshadow the real progress being made in those fields, and the perpetual disappointment and unrealistically high expectations hurts enthusiasm and possibly funding.

        They later say that it could be upgraded to write 500TB in 60 days. That would be pretty rad, especially if the form factor isn't too unwieldy and read speeds are decent. This could render backup...

        They later say that it could be upgraded to write 500TB in 60 days. That would be pretty rad, especially if the form factor isn't too unwieldy and read speeds are decent. This could render backup services effectively obsolete.

          If my maths are correct, that's about 96.5 megabytes per second. Slow compared to modern hard drives, but with 500 TB of storage space you wouldn't catch me complaining.
