First CDs would take hour and a half to write with a laser. Once engineers take over the tech, it will might get faster.
replyIf they get the read speed up to a couple of GBit/s (~100x current max write speed), 4.8TB might be a good fit for 32k movies.
replyWrite speed is probably the least important metric for people that are considering something like this. After everything with storage and longevity is taken care of, improving write speeds is a nice to have, but not the important part.
reply>This seems decent?
replyDefinitely. If it actually achieves those speeds it's perfectly reasonable for long-term/cold storage.
Depends somewhat on the read speed, too. Extreme example: if that is one bit per year, it doesn’t matter that you can write stuff on it.
replyI imagine if you can use lasers to etch at that speed, you can use them to read at similar speeds as well.
