If you would purchase a couple of Raptors (faster spin speed), then raid those, you should see a nice gain. Do they fail more, well, that depends upon how you judge it. With two drives being in the array, there is a slightly bigger chance of failure because you have to have two drives that do not fail, so the failure has actually two chances to fail instead of one. So, you can call it what you want, but the more components in anything, the higher of a chance that something can go wrong.

That is not because of the array or the drive, but just plain common sense. The more parts, the bigger chance of failure. That is my opinion.
