NVMe will take off with PCIe4
AMD launches Rome based microprocessors this year, which come with more PCI lanes and PCIe4.
Intel -which still makes up the bulk of the x86 business - is at least a year behind AMD, but will also drive the NVMe boost.
NVMe fabric design is just beginning to catch on, but really, you're going to get faster performance from server-based NVMe than you'll ever get from external SANs as it's closer to the CPU.
