No, it's not just you, and judging by how strongly I feel about it, it's not just the two of us.
When I find a flash drive that's been sitting for a few years and I can still read it I always feel a sense of relief. I feel like everything we've got today is too advanced to maintain the slightest glitch.
I would love large write-once flash disks that would last for 20+ years in storage. There's a ton of archival data out there.
I have a hard time imagining this is useful or good for many apications, as I just expect endurance to be awful. But given how much data warehousing we do, there is definitely some potential for this, as a post-nearline storage.
This also seems like something zones storage would be so good for, to help reduce write-amplification concerns. Alas there are still zero drives one can go slap down a credit card & purchase.
128 bits =/= 128 levels
You're mixing up the units. 128 bits require 2^128 levels to represent. 128 levels can only represent 7 bits. The only way the two are related is the number "128", albeit with different units.
