NVMe

Non-Volatile Memory Express

Definition

NVMe is a storage protocol designed for SSDs that communicates over PCIe, delivering far lower latency and higher IOPS than the SATA interface it replaces. Cloud instance store volumes and high-performance block storage tiers use NVMe to deliver hundreds of thousands of IOPS with sub-millisecond latency.

NVMe instance storage is ephemeral — data is lost when the instance stops.
