Questions tagged [nvme]

NVMe is a communications interface/protocol developed specially for SSDs (Solid State Drives).

NVME, which stands for Non-Volatile Memory Express, is a specification developed specifically for accessing high-bandwidth SSDs over the PCI Experess bus.

The SATA bus, which was designed primarily for HDDs, became increasingly inadequate for SSDs as they became faster and faster with each subsequent release. Thus, NVME was born.
