So with the new bios upgrade this motherboard now supports NVME installation. I want to buy these two items: QNINE NVME Adapter PCIe x16 with Heat Sink, M.2 SSD Key M to PCI Express Expansion Card, Support PCIe x4 x8 x16 https://www.amazon.com/dp/B07F9RBP5...olid=1SYDWH66RTUXX&psc=0&ref_=lv_ov_lig_dp_it Inland Professional 1TB 3D NAND M.2 2280 PCIe NVMe 3.0 x4 Internal Solid State Drive https://www.microcenter.com/product...80-pcie-nvme-30-x4-internal-solid-state-drive I have some questions: 1) Is the above SSD "M-key"? The adapter I listed above only works with M-key SSDs. 2) Here is the link to my motherboard: https://www.asrock.com/mb/Intel/Z87 Extreme4/#BIOS The description states it has: 3 PCIe 3.0 x 16, 2 PCIe 2.0 x 1 So my question is just how many of the above adapters and NVME SSDs can I install? I have a XFX R9-FURY-4QFA RADEON R9 FURY X 4GB HBM GPU installed which I believe takes up only 1 PCI slot. It would be really neat if I could install 2 or maybe even 3 NVMEs with the adapter since they are so much faster than SATA SSDs.
