> Close to a petabyte of data is generated every second True, but misleading. Most of this data is processed realtime in hardware within the detector(s) and the majority discarded (proton-proton collisions are messy with a lot of uninteresting debris). I believe the volume of data actually written out to disk is ~1GB/sec. [Edit: it's actually 0.5GB/sec http://public.web.cern.ch/Public/en/LHC/Computing-en.html http://public.web.cern.ch/Public/en/LHC/Computing-en.html ]
