Visual sky survey telescopes can produce hundreds of terabytes of data per night they operate. Radio telescope can produce tens of petabytes per night. The SKA-Low telescope could theoretically produce 9 exabytes per night.

To put that in perspective, the total daily internet traffic ranges between 25-35 exabytes per day. If you fraction that to the ten hours a telescope would operate SKA-Low could double the amount of data transmitted globally on the web while it's recording
