NVM Express
scalable, efficient, and industry standard, What is NVMe Technology? The NVM Express® (NVMe®) specifications define how host software communicates with non-volatile memory across multiple transports like PCI Express® (PCIe®), RDMA, TCP and more. It is the industry standard for solid state drives (SSDs) in all form factors (U.2, M.2, AIC, EDSFF). NVM Express is the non-profit consortium. Learn More Who

NVM Express (NVMe, Non-Volatile Memory Express) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface specification for accessing a computer's non-volatile storage media usually attached via the PCI Express bus. The initial NVM stands for non-volatile memory, which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCIe add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low latency and internal parallelism of solid-state storage devices.
Architecturally, the logic for NVMe is physically stored within and executed by the NVMe controller chip that is physically co-located with the storage media, usually an SSD. Version changes for NVMe, e.g., 1.3 to 1.4, are incorporated within the storage media, and do not affect PCIe-compatible components such as motherboards and CPUs.
