Glacier in particular seems to attract the speculative fascination. Do people not realise the name is not in jest, it really is done with graphene-doped room-temperature ice crystals and laser interference lithography?

We used to joke among ourselves that actually it was done using vinyl records. Have you seen how many vinyl records you can fit into a single rack?

Added bonus, 9 out of 10 customers actually preferred the feel of their data when it is restored.

I liked the story that the truck-mounted Snowball came from Glacier tech. Amazon has been putting data on a truck and then driving it around Virginia. The delay in reading it back is the time it takes for the truck to arrive at a datacenter and plug in. :)
