Real World Tests:
For our real world tests, I decided to check some file transfer speeds. We read(and wrote) from a 4GB RAM disk which was pretty much the limit as I had just 8GB. We use a RAM disk so that the other drive does not become a bottleneck. I used a 3.5GB compressed file for these tests and measured the time to transfer. These are not perfect tests as its too short a test, but the times should give you an idea of things.
Again, do suggest some more real-world tests that you would like to see.
