BTW, we were doing full-speed tick data collection and real-time trading analysis in the nineties, on machines that my current cell phone would leave in the dust. The market data volume has grown a lot since then of course, but the price of hardware has fallen a lot more.
Trading volume always grows to where it's just possible to keep up with it using a well designed app on the fastest hardware available. If you're always faster than someone else there's money to be made from them using that fact. The continuous arms race for the fastest scanning and execution platform keeps volume moving upward in lock step with what hardware is capable of.
