NVM Express (NVMe)

NVM Express (NVMe), or Non-Volatible Memory express, is a logic device interface specification. It is a specification of the bus transfer protocol based on a logic interface of a device similar to AHCI (the application layer equivalent in the communication protocol) and is used to access non-volatile memory connected via the PCI-Express bus (PCIe).
NVMe SSDs (Solid State Drive) are important components for storing data in a server environment, solid state drives are ideal for high-speed applications, while hard drives are suitable for large-scale storage solutions. These two components must always be replaced in server maintenance work.
