> At the press conference, city officials shared 80 exabytes worth of heart ultrasound videos, according to one company that participated.

Do you know anything about this? 80 exabytes is an insane amount of storage and is orders of magnitude larger than any dataset I'm familiar with. I believe Common Crawl is in the petabytes range, and [0] describes training a neural net on 300 million images (which would be 300PB if each image was 1MB, but I suspect images are smaller). 80 exabytes is 80 million terabytes and would cost hundreds of millions to store.

My guess is that some journalistic error occurred here, or perhaps someone confused "80 exabytes of data are generated during heart ultrasounds" with "we've stored 80 exabytes of heart ultrasound data".

Yes we are in the center of this. We are analyzing all of that data ourselves. The hospitals in china (each one) emits petabytes of data themselves.

There are about 1600 hospitals in all.

Real time ultrasounds get synced to the cloud via devices planed in rural villages.

80 exabytes is not "journalistic error". We are building one of the largest AI research centers in china to accomplish this.

Is that compressed or uncompressed size?

Raw data. Pre processed is always smaller in practice.
