Yes our ECU's definitely do use flash as brought up. Someone a while back on another board actually posted an ECU dump from their Si's ECU that they got from the HDS system.

I'm an IT guy. In terms of amount of storage space, the data it collected could easily be held in a reasonably sized flash space amount. There is a finite amount of driving time that can be recorded before it will start overwriting itself, BUT it could easily hold 20 minutes of driving time before and after each and every time you redline your car over the entire course of its life. Well, assuming you aren't constantly redling it. The data I saw just didn't amount to something that would take up huge amounts of space. It was mostly just date and 20-30 sensor readings.
