Lenovo iq270ms board includes M.2 and SATA connections.
Does filling the M.2 slot affect any SATA connections? I'm trying to figure this out since I haven't checked online. I just bought a free Lenovo M910 i7 6700 and plan to use it as a home server. I want to add SSDs, run Plex on NAS, and store photos elsewhere. No one has mentioned this before.
I notice no clear indication of shared resources. The Z270 chipset appears to be the central component, with bandwidth likely distributed across the DMI. It's conceivable that the CPU's PCIe expansion is shared with the M.2 slot, or that everything operates on the unified DMI bus via the chipset. My Z97 ROG Impact board demonstrates this by connecting to both a 4x M.2 and a 16x slot, reducing the latter to an 8x configuration when M.2 is active. I believe the M.2 drive probably uses the same bandwidth as the main PCIe connection through the CPU or functions independently on the shared DMI 3.0 channel.
