NVMe (Non-Volatile Memory Express)

NVMe is a high-speed storage protocol designed for solid-state drives to maximize performance over PCIe.

What is NVMe?

NVMe (Non-Volatile Memory Express) is a storage protocol designed specifically for solid-state drives (SSDs) to take full advantage of the speed of flash memory over PCIe interface.

NVMe advantages

Low latency, High throughput, Parallel I/O, Direct CPU access.

Common misconceptions

"All SSDs are NVMe" — SATA SSDs still common
"NVMe is always needed" — Depends on workload
"NVMe is just faster SATA" — Different architecture
