A non-volatile memory express, or NVMe for short, is an optimized and scalable storage protocol that connects a host system to its memory subsystems.
NVMe minimizes CPU overhead on data transfer and provides capabilities of changing priorities based on workload requirements. You can use NVMe for non-volatile memory, and it supports up to 64K entries for each I/O queue. System configurations and expected workloads control NVMe.

NVMe can begin, execute, and finish multiple I/Q queues simultaneously and optimize for speed and reduce latencies.
