CERN’s Large Hadron Collider experiments create 1Pbyte per second, in the form of images of particle collisions. CERN has stored a 100PB archive, and adds another 27PB per year.


New experiments will push that to 400PB per year by 2023, forcing CERN to expand from its Geneva data center (actually across the border in France) to one in Budapest, Hungary.
