Having done some research on the a similar product (the iRam by GigaByte) I doubt that you will see speeds of 8000 time faster than a 10,000 RPM drive, because, as other have stated above, you are still going through some sort of drive interface and bus. Data-throughput speeds are limited by both of these (Sata on PCIx is 3Gbps and PCI is 1.5Gbps). In fact on just moving data back and forth on a product like this, should show no or little improvement (according to reviews of the iRam, that is the case atleast).

Where a product like this should show its muscle is an application that requires lots of small, fast read/writes. Why? Because it can do multiple read/writes at a time; no waiting for the last operation to complete. So this is more suited to housing files like a database (in fact the only implementation of the iRam I have seen successfully speed up operation in any signifigant manner is on database calls).
