You never know what you’re going to learn in a LowEndTalk thread! LET member @Ahfaiahkid shared a link to an interesting news article about some research going on in Japan. Researchers there announced they’ve developed a method to make ultra-thin diamond wafers capable of storing 25 exabytes (!) of quantum memory.
As the article observes, that’s a billion Blu-Ray disks! Well, if you’re still rocking an optical lifestyle. For me, just the phrase “25 exabytes” is enough. 1 exabyte = 1,000,000 TB.
Boffins have apparently been struggling to get the right nitrogen-vacancy center and…no, I don’t understand it either. Just give me cheap storage.
“The team hopes to commercialize these diamond wafers in 2023,” according to the report. Sounds good to me. I’ll hold off upgrading my home NAS until then.
