MODERATORS
Read and single write capability is an interesting proposition for archival purposes. 8-10MB/s write and 50-200MB/s read speeds
I do photography, and I like to keep the original RAW photos from the camera. So, this sort of thing would be perfect for me. I don't really need fast write access, since I just want to back the photos up and it's not time sensitive.
Archival CD-burning is back, baby!
Wonder how rough bit rot would be though.
What form would that take? They seem to indicate lifetime on the centuries, similar to expectations for M-DISC.
Gonna guess glass deformation over time is going to come into play (really (like millennia) old windows get thicker at the bottom), probably why the quartz version of this is speculated to be good for millions of years. And of course breakage. The drives will fail first.
Sucks to be Microslop sitting on this for years and years and China comes along and eats your lunch. Ha Ha.
Hopefully a story soon to be repeated with RAM and then chips, about time there was real competition and innovation in this space, too many cartels due to high capex siloing. This looks more like CDs, could be everywhere in a few years.
Glass flowing to be thicker at the bottom is a myth.
Yeah, I've heard that and I've seen pictures of examples, dunno. Personally, anything beyond a century is irrelevant anyway.
The window panes were cut from irregular sheets, and they were simply installed with the thicker part at the bottom, for structural integrity.
It was a manufacturing quirk.
Spin them once daily or weekly. As long as they're balanced that should randomize the gravity vector.
It's also almost certainly a different composition than century old glass panes made for buildings. So the material itself might mitigate this issue
Do you mean rotate them? Spinning them up would make it worse.
No cold flow would move mass to the lower side when being held vertically causing an imbalance. If you spin up a balanced disk it comes to rest at a random angular position or motor pole.
Randomizing the side of the disk that is down regularly and with relatively short intervals keeps the average displacement of mass due to cold flow near zero.
Of course rotating would also work but that would require a motor with fine positional control when reliable systems thrive on simplicity.
Like the other user mentioned, glass warping/deformation. Although I'd reckon kinetic impacts, tremors, or actual drive failure would occur first (the real question is what are the maximum tolerances before a read/write fails or ends in data corruption).
The data is burned into a piece of glass with a laser. It doesn't use a dye to store data like a CD-R. I doubt bit rot would be much of an issue. With that much capacity, you could use lots of forward error correction though.
