The RevoDrive X2 is essentially an original RevoDrive with a daughter card piggybacked on top. This daughter card adds two additional SandForce controllers and room for more memory chips, bringing the total controller count to four. A RAID0 configuration manages the four controllers and memory chips, resulting in what OCZ proclaims is a blazing fast PCIe SSD solution. We were pretty impressed with the original RevoDrive and can only wonder if the follow-up product is equally as impressive.
