NVMe disks are SSD type disks with the main difference between them and regular SSD disks being the way with which they are connected to the server's motherboard. The connection happens using the PCIe bus standard which connects straight to the motherboard like we see with things such as graphics cards. That method of connection makes NVMe disks faster due to the lack of cables thus ensuring that higher speeds are attainable when it comes to data transferring to and from the SSD Disk.
