These results just reflect my setup, which I would think is a somewhat typical setup. I would also think that most people don't have multiple SSD in RAID 0 to install from. As far as raiding two OCZ drives showing better improvements, that is understandable because the performance of 1 OCZ (core series probably) drive may not be able to deliver the data fast enough for the intended program, so when you add a second drive it would show a gain(or larger gain).
