Scientists are ready to handle the increased data of the current run of 
the Large Hadron Collider
> http://www.symmetrymagazine.org/article/july-2015/more-data-no-problem

> Physicist Alexx Perloff, a graduate student at Texas A&M University
> on the CMS experiment, is using data from the first run of the Large
> Hadron Collider for his thesis, which he plans to complete this year.
> When all is said and done, it will have taken Perloff a year and a
> half to collect the computing time necessary to analyze all the
> information he needs—not unusual for a thesis.

> But had he had the computing tools LHC scientists are using now, he
> estimates he could have finished his particular kind of analysis in
> about three weeks - the equivalent of having 26 times the computing
> resources. Although Perloff represents only one scientist working on
> the LHC, his experience shows the great leaps scientists have made in
> LHC computing by democratizing their data, becoming more responsive
> to popular demand and improving their analysis software.

> A deluge of data

> Scientists estimate the current run of the LHC could create up to 10
> times more data than the first one. CERN already routinely stores 6
> gigabytes (or 6 billion units of digital information) per second, up
> from 1 gigabyte per second in the first run.

> The second run of the LHC is more data-intensive because the
> accelerator itself is more intense: The collision energy is 60
> percent greater, resulting in “pile-up” or more collisions per proton
> bunch. Proton bunches are also injected into the ring closer
> together, resulting in more collisions per second.

> On top of that, the experiments have upgraded their triggers, which
> automatically choose which of the millions of particle events per
> second to record. The CMS trigger will now record more than twice as
> much data per second as it did in the previous run.
