2 PCI Express SSD, PCI Express is more like a SATA SSD on steroids In a theoretical mad dash to the finish line, an PCI Express SSD

The only distinction would be TLC, which results in 3 bits being stored per cell, and usually results in slightly lower speed and durability

nvme and m2 slot difference SSDs are a type of semiconductor-based storage used with flash storage, and NVMe is a protocol for data transfer with reduced system overheads

nvme slot vs m2 pcie is about 4x faster The add in cards plugged into a X4-X16 pcie slot will have some sort of adapter
