Hi,
As to the additional cost of RAID0, I really don't see much there. All quality motherboards seem to retail for very similar prices (perhaps $40US difference top to bottom). The cost of two drives is about the same as the cost of one twice as large. For all but the lowest cost systems, RAID0 doesn't appear to be that big a percent differential. A modular power supply will often make a bigger price difference, giving in return nothing that a few cable ties and some technique doesn't do as well. But, of course, that's my opinion, others will see it differently;)

You can probably find some hardware vs. software RAID comparisons at storagereview.comOK. Thanks. My error was in thinking that all RAID controllers would use hardware parity and striping, especially since the components for these functions are simple, cheap, and ancient. Guess I've got some homework to do.

Looking over the test results, it appears that in many of the applications tested, including the game loads, the program was performing some other function to soak up time while accessing the disk. Thus, the test became one of the speed of the other, non-disk, function.
