I have some questions: How fast are read and write operations and random access? What are the expected prices, once it hit mass production for the average consumer? And how long is expected to take until this happens?
From the article it seems to be write once and then it is read only. As reading requires mechanical movement (for now), I would guess that random reads are quite slow.
So I guess the first application would be archives, and then later it could be used like a CD.
Which would beat current LTO tape, that’s the real goal they have. It’s not replacing hard drives, random read time isn’t important, it’s archive. Tape can be real finicky to store at volume, but it’s amazing at archiving. A single tape can now natively hold well over 20TB and doesn’t need to be kept powered on.
On the one hand, I'm slightly disappointed because ever since I first heard about this tech I've been lusting after having a quartz drive in my own computer so I can burn billion-year "disks" of my stuff. :) But on the other hand, at least this is good news that the tech is progressing toward actual use. It's another step along the way.
It would be prescient for movies shot before 1996.
The concept is to store data optically in non-photosensitive transparent materials such as fused quartz, which has high chemical stability. Recording data using a femtosecond-laser was first proposed and demonstrated in 1996.
