The hard drive I used was a Seagate Barracuda so it’s going to be slower than the F3 but I think the biggest difference is that my system image was of a fully loaded OS (Win 7/ 64) with apps and games installed. That seems to make big difference as I incurred 400MB reads vs 100MB on you F3.

The total reads/ IOPS on your SSD raid are also around half of mine.

Trying to compare my results with yours is going to be difficult/ impossible without using the same system image. The key however is do you see similar outcomes between different configurations as I did.
