You're referring to NVME based M2 SSDs, correct? But yes if the SSD is PCIE spec then of course the speed will be less when used on PCIE

SSD , NVMe PCIe and NVMe PCIe which one is better 2 SSDs : 80x22mm, 60x22mm and 42x22mm, 30x22mm Hardware Requirement: Available PCI-ex1 slot, or PCI-e x4x8x16 Slot on Mainboard

nvme and m2 slot difference That said, although older PCI e peripherals will work on a PCIe 4 slot, their speed will be limited to their generation's specifications For

NVMe SSDs via a single x16 PCIe slot adapter speeds, with backward compatibility for PCIe slots

nvme m2 slot Two types of PCIe slot on an Asus H81M-K motherboard Various slots on a computer motherboard, from top to bottom: PCI Express x4; PCI Express x16; PCI Express

vs PCIe Bandwidth For example, a GPU has traditionally utilized 16 lanes, while PCIe NVMe drives would consume an additional four lanes
