this new ultra-high density optical data storage looks pretty damn cool

1 petabit is 128 tb

"All in all, a DVD-size version of the new disc has a capacity of up to 1.6 petabits—that is, 1.6 million gigabits. This is some 4,000 times as much data density as a Blu-ray disc and 24 times as much as the currently most advanced hard disks. The researchers suggest their new optical disc can enable a data center capable of exabit storage—a billion gigabits—to fit inside a room instead of a stadium-size space."

zut alors! c'est incroyable! seems like a win for big data and surveillance more than a layperson tho.

tech is for everyone. i use the same harddrives in my servers that big tech has in theirs.

"Currently, he says, the new discs have a writing speed of about 100 milliseconds"

What, per bit? Do about 1 byte per second? That's can't be right...

right. i couldn't find the specific data with a quick cursory search but i did find this:

"However, they caution that although this increases the areal density of storage substantially, improvements in writing speed and energy efficiency are needed for commercial viability. This could be accomplished by using a femtosecond laser beam with a higher repetition rate and a more sensitive photoresist than those used in the current system.

This means the nanoscale optical storage system is some way off from any commercial availability of drives and media, but the researchers assert that such products should prove less costly than current state-of-the-art optical disc libraries and hard drive arrays for meeting the vast data storage requirements of the AI era."

A datacenter? Using write-once optical storage media?
