PCIe vs PCIe NVMe SSDs: What's the difference? m2 pcie 4 0 in 3 0 slot PCIe 4 is backwards compatible with gen 3, 2 & 1, and you will get at least the same performance from putting a drive in a slot as you m2 expansion slot Gen 4 is faster than Gen 3

m2 expansion slot Hallo, wenn der Formfaktor passt , kannst du auch eine PCIe SSD in einem PCie betreiben, da

m2_1 slot A single PCIe slot can now support x16, x8, x4, x2, or x1 lanes For example, PCIe x4 indicates a Gen 3 expansion slotcard with four lanes  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
