Your setup includes a high-end CPU and multiple NVMe drives. Running the Samsung Evo 860 and SN550 alongside a PCIE card will work, but expect some performance trade-offs. The Evo 860 offers good speed but may feel slower with heavy workloads, while the SN550 provides solid performance for everyday tasks. Overall, you should maintain smooth operation, though latency might increase slightly compared to using a dedicated M.2 NVMe drive.
The motherboard features two M.2 slots. Issues with B and M&B keyed SATA M.2 drives prevent them from operating at higher speeds regardless of settings.
Consider your options carefully. You bought a new SSD yesterday and now have a Samsung 980 in slot 1. Your existing 860 Evo, which was also in slot 1, isn't working because of an M.2 key issue on slot 2. Think about whether you can swap the drives or if you need to replace the old one.
I use three M.2 drives on my B550 and everything functions well.
Slot 2 is M&B? I recall M&B should work with just the m keysticks, but it runs slower at SATA speeds. It seems the second slot is still functional even though it’s slower. There might be a formatting problem, but I’m unsure how to fix it if it doesn’t install properly. Perhaps take out the new card, put the M&B stick back in slot 1, boot from a USB so the stick isn’t the boot drive, and wipe it. Not sure if that would help.
No way, don't let go of that 400GB of recordings and CAD files.
Slot one contains M&B and SATA. It uses PCIe 3.0. The second slot is labeled with the M key or the Just B key—I don’t recall. However, this setup doesn’t support SATA.
Maybe not, since your device only works with PCIe 2.0 and that slot isn't compatible.
