Researchers have developed a Very Big Disc™ that can store up to 200 terabytes of data and may represent a return to optical media for long term storage
@NorthernInvader I suspect they will have lots and lots of trouble reading and writing to it. The old tech literally worked by burning away part of the disc. That won't work here especially at that scale. The layers are simply too close together. Maybe they will find a way though.
Also, they say the discs are stable. I bet they are *physically* stable like any CD. I doubt very much they are highly stable in terms of data integrity. 1 nanometer spacing between cells is 😬.
@NorthernInvader Also, what happens if you drop it?
💥 Oops.
Layer 39 mostly collapsed into layer 40 but it's OK. Only a few terabytes of data were lost. It's a good thing we backed up layer 39 on layer 79. We halved the data storage but the redundancy will always save us!
💥 Oops again...
@danielbsmith I guess we'll have to wait and see
