Can you figure out how much music these new diamond memory discs can hold?

When the boffins refine things, quantum computing is going to change so much about the world. So much data is going to be generated that scientists are looking for new forms of memory. Some Japanese engineers have just come up with something pretty cool.

Per New Atlas, these people have created a 5-cm wafer made up of ultra-pure diamond (called Kenzan Diamond) that could be used for quantum memory. They say one of these choking hazards can store the equivalent of one billion Blu-Ray discs.

Here’s a math problem if you need a timesuck today. If a standard single-layer Blu-Ray can hold 25 gigabytes of data and the average size of an MP3 is five megabytes, how many songs could be stored on one of these new diamond discs? You first.

Let’s look at it another way: Kenzan Diamond disc can hold 25 exabytes of data. And to illustrate how much that is, Google stores just(!!!) 10 exabytes of data.

But these discs will soon be too small. By 2025, it’s estimated that 463 exabytes of data will be generated by people every day. That will require 18.52 Kenzan discs every 24 hours. Then again, these things are only 5 cm across, so. But would you want to index that database?
