As motherboard manufacturers unveiled their new Intel 9 Series products one after another, we can see the proliferation of PCIe Gen2 x2 M.2 interface on Desktop motherboards very clearly. However, ASRock Inc. took the lead among other competitors once again. This time it's the Z97 Extreme6 which boasts "Ultra M.2 PCIe Gen3 x4" socket stands out. With its doubled transfer bandwidth, ASRock Ultra M.2 is able to completely break through the speed limit of SATA3 6 Gb/s and blow others away!

The Secret of Ultra M.2
Ultra M.2 is one of ASRock's creative innovations. Compared to normal M.2 with PCIe Gen2 x2 bandwidth, ASRock is the first one in the world to double the M.2 bandwidth to PCIe Gen3 x4! Furthermore, the layout of Ultra M.2 is also specially designed. On a regular motherboard design, the signal route starts from the M.2 device, goes through the onboard chipset, and finally reaches CPU. In contrast, by connecting the M.2 interface to CPU directly, ASRock Ultra M.2 has lower latency and pushes the I/O speed to a new level!
