Anybody amongst the fast growing community doing big data, a field no
longer reserved to big corporations :
- Small teams doing stock market research, where the number of
transactions in a single day far outnumbers your figures: Doing proper
backtesting in a reasonable amount of time makes it imperative to
store data in Ram ;
- Research teams trying to discover unknown correlations between
already approved medicine and pathologies for which no effect is yet

The list could go on forever. The point is that thank's to Internet
and high bandwidth optical lines, more and more people have access to
large datasets, and most of them cannot afford access to mainframes.
Hence the necessity to store as much data as possible in central
memory before analysis.
