"The idea behind Intel's SRT was that you could use a smaller SSD drive, say 20GB, and combine that with a larger traditional mechanical drive and the SSD drive would be used as cache which would in turn be faster than just having everything run off the mechanical drive. Overall, it was never going to be as fast as a true SSD-only drive for everything, but it's never going to be as expensive either.
Recently Chris took the time using the board we have here today, the Z68XP-UD3-iSSD to see just how Intel Smart Response Technology goes. Today we'll be taking a look at the rest of the board and summing everything up. What makes this board stand out so much over the normal way you'd go down the ISRT route is that it offers an onboard 20GB SLC SSD drive via mSATA."
