Question PCIE Bifurication / Additional Storage

[Gamefreaknet]

Does a motherboard need to support PCIE bifurication to support use a x4 or x8 or x16 slot for nvme storage drives? I intend to get a new PC however I do know some motherboards disable SATA slots if you use NVMe slots. Most builds I would prefer to have option to use SATA (III) SSDs as where I am SATA drives are generally cheaper than NVMe(s)
Also as of current I have never had an issue with a SATA drive as compared to NVMe drives (had 2 NVMe drives fail me up until now - 1 Samsung 970 Evo Plus and a Kingston NV2 so I dont think its due to unreliability)

Any slot can take an adapter, but some may take lanes from the GPU or conflict with other things such as PCIe slots, SATA ports, M.2 slots, etc. You need to check the manual. For an adapter with more than one drive, you need either bifurcation support (explicit, some boards can only do it in the discrete/primary GPU PCIe slot, some can do x4/x4 in a second slot, etc) or an AIC that does it on-board (I recently posted a review/look at one of the latter but also own the former). You can use x1 adapters (vertical too) as well, you lose bandwidth but keep the latency benefits of NVMe, and I use these as well.
