I see from an excellent thread explaining the various runs that the data is released some time after the initial time of the run. I'm aware of the very powerful computers used so I assume there is a huge amount of data to process. My question is how much data is processed in a single, eg. gfs run?

(I wasn't sure whether to post this in the hardware forum so please move if necessary)

I can't answer the question directly, but a 125x125km 60 level ECMWF reanalysis generated 1500GB a year - I *think* that's one chart a day, but I don't know.
Back in the days of the Cray twins, the Hitachi mainframe was needed as a front-end processor - it was noticeably slower when the run started pouring forth.

You might find and answer on the GFS and ECMWF sites - or a Google scholar search.
