m 2 slot with pcie x4 lanes   Dan m2 sata vs nvme slot

Generally speaking, if you install an SSD in the chipset slot, you're going to see it use 2 lanes worth of bandwidth most of the time

Most of those cards are x16 and their switches split to x4x4x4x4 But there are x8 cards with 4 sockets which then split to x2x2x2x2 Check 2 SSD to PCIe x16x8x4 Card with aluminum heatsink is the perfect solution for faster transfer speeds! Enjoy extremely fast transfer speeds via PCIe lanes SSD
