Hetman6, I don't really think that's accurate:
"As a note, the tests don’t specifically check to see if the underlying storage device is an SSD or not. "
If your non-SSDs fly, on a raid or not, I'm sure it'll put you in high end range. It would be silly if it didn't, considering the relative importance of HDD speed in gaming. I mean to say, as long as your HDD is in a certain range it won't bottleneck your other high end expensive hardware, and that range isn't only limited to SSDs. Yet. It will be later on I'm sure.
