Current write speed (No read speed given):
Blu-ray (1×) ~36 Mbit/s
MS-Glass (single beam) ~25.6 Mbit/s
MS-Glass (multi-beam) ~65.9 Mbit/s
That's ~7-18 days per 120mm x 120mm medium (4.8TB).
Glass prices stable for now. Also, the authors make no statement about horizontal vs. vertical storage.
Thanks for digging this up. Every "scientists create new storage medium" is always a disappointment when you get to see the write speeds. This seems decent? At least in "raw" numbers there's nothing obviously making this useless. Let's hope they have a path to quick commercialisation and make it available. If there's any DC adoption will be the real test, I think.
