How much data?
Since BaBar started operation in May, we have recorded 7 million events.
- 4 more years’ running and continually improving luminosity.
- Eventually record data at ~100 Hz; ~109 events/year.
- Each event uses 100-300kb.
- Also need to generate 1-10 times that number of simulated events.
Recorded 5 Tb
- Expect to reach ~300 Tb/year
- Ie. 1-2 Pb in the lifetime of the experiment.
