    If only two SSD's are connected to the CPU what is the other connected to?

    How is the 8700MB/s acheived?

    Normally all SSDs are connected to the cpu through the pch, so they all have to compete for bandwidth. this removes two from the pch and connects directly to the CPU, so everything is operating at max speed instead of bottlenecking. bad news is the main effect for most users is going to be that they moved their bottleneck to another piece of hardware or the network.

    Thanks for the answer Eric. What is likely to be bottlenecked in that environment?

    If you're downloading things, the network or host server, if you're transferring files to another drive, the other drive.

    You wouldn't have any bottleneck internally as the speed is already too fast for everything you do.
    The only bottleneck that you would be getting are all external related.

    I have 2x500GB Samsung 960 EVO's in RAiD 0 on my laptop but DMI limitations prevent read speeds to a max of 3,400MB/s.

    Hypothetically, if the 2 drives were directly attached to the CPU removing the pch/DMI bottleneck what speed would they reach in RAiD 0?

    Is there a mod to do this?

    I see, so you do have an internal bottleneck with it, because you were supposed to get 6500MB/s+. So this is likely a hardware limitation and you can't really boost it any further.
    Is it happening with ASUS G703? Or MSI GT73?

    The limitation is with Intel's CPUs. DMI is a chip limitation.

    Currently using an AORUS X5V7 but considering the ASUS G703.

    ASUS G703 has no bottleneck so you can get higher speeds.
