Thanks for the advice! Sorry, forgot to give more information about my server I use a
Prime B550M A (wifi) motherboard - 2x PCIe 3.0 1x slots
Ryzen 5500
16 GB RAM
NIC card = Intel X540 t2 (recently purchased)
LSI HBA card I planned to purchase = LSI 9211-4i - PCI 2.0
Could I use a M.2 to PCIe riser 8x? My M.2 is PCIe 4.0
