Although the 9 series chipset is basically an improved version of the vest can be seen as 8 series chipset one of the few bright spots regarded as a function of M.2 interfaces. The current M.2 interfaces are generally PCI-E 2.0 x2 channels (there is x1 channel), the theoretical speed of 10Gb / s (bandwidth of 1GB / s), much faster than SATA 6Gbps. If you think this is not fast enough, then take a look at ASRock Ultra M.2 Interface, using a PCI-E 3.0×4 channel speeds of up to 32Gbps, close to 4GB /s of bandwidth.
ASRock Ultra M.2 Interface: PCI-E 3.0 x4 channels, 32Gbps speed
ASRock Ultra M.2 the main difference in getting this speed is the source channel PCI-E, PCI-E channel source current M.2 interface mostly Southbridge chipset 8-channel PCI-E 2.0 The two, while ASRock M.2 Interface PCI-E channel directly from the CPU, the Intel processor is now widespread support PCI-E 3.0 x16.
As a result, the speed of the Ultra M.2 interface as high as 32Gbps, almost six times than PCI-E 2.0 x1, 3 times more than 2.0 x2, and ASRock with Samsung XP941 PCI-E x4 M.2 Interface SSDs do the test, speeds of up to 1.16GB/s, while the standard M.2 Interface PCI-E 2.0 x2 channel speed is only 790MB/s, the speed increase of 46%. Even use the same PCI-E 2.0 x2 channels M.2 SSD ASRock M.2 interface speed should be higher than 8.8%.
ASRock Z97 Extreme 6 motherboard supports super M.2 interface, the more high-end motherboards will also support this interface.
They should not be an official test scare, M.2 Interface PCI-E 3.0 x4 channels only looks very nice, CPU-PCI-E 3.0 channel did not say,
Of course, we have to like a new idea from ASRock , if you really have such enthusiasts, just super M.2 interfaces can also come in handy.
