Every five seconds, LHC collisions will generate the equivalent of a DVD-worth of data, that’s a data production rate of one gigabyte per second. To put this into perspective, an average household computer with a very good connection may be able to download data at a rate of one or two megabytes per second (if you are very lucky! I get 500 kilobytes/second). So, LHC engineers have designed a new kind of data handling method that can store and distribute petabytes (million-gigabytes) of data to LHC collaborators worldwide (without getting old and grey whilst waiting for a download).
