Differences between NVMe, AHCI, SATA, PCIe, and M2

Differences between NVMe, AHCI, SATA, PCIe, and M2 m 2 and nvme slot difference The 970 EVO is in the M2_1 slot and the new SN850X is in the M2_2 slot I know that the SN850X is Gen4 and significantly faster, I got it on a m2 slot is a new form of connectivity that allows a SSD to connect directly to the PCI-E bus allowing for theoretical speeds as high as 2GBs

m2 slot Note: Most M Key sockets on laptops are backward compatible with SATA bus, but some M Key slots on desktops only support PCI-E bus 2 slot on

m2 nvme slot Won't matter much, but generally you want your OS on the fastest drive you have, or in the fastest slot you have The difference from 1 slot two NVME SSD It doesn't matter which slots they are put in, there is negligible performance difference
