A friend of mine works at Fermi lab. The D0 project generates ~2TB every
of data in about .001 usec. This volume gets filtered down to about 10
GB through a huge pile of systems (my friend wrote some of the physics
event filtering code) and finally get dumped to an array of tape drives.

This process repeats every 20 seconds they have beam time.
