NVMe

释义 Definition

NVMe（Non-Volatile Memory express）是一种为SSD（尤其是基于 PCIe 的固态硬盘）设计的高速主机控制器接口与通信协议标准，相比传统 SATA/AHCI 通常具有更低延迟、更高并发与更高吞吐。（也常指“NVMe 固态硬盘/接口”。）

发音 Pronunciation

/nvim.i/

例句 Examples

I installed an NVMe SSD to speed up my laptop.
我安装了一块 NVMe 固态硬盘来加快笔记本电脑的速度。

Because NVMe supports many parallel queues, it can handle heavy I/O workloads much better than older SATA drives.
由于 NVMe 支持大量并行队列，它在高强度 I/O 负载下的表现通常比旧的 SATA 硬盘更好。

词源 Etymology

NVMe 是缩写，来自 Non-Volatile Memory express：

Non-Volatile Memory 指“非易失性存储器”（断电数据不丢失，如闪存）。
express 借用了类似 “PCI Express（PCIe）” 的命名思路，强调高速通道与低延迟特性。
该标准由产业组织 NVM Express, Inc. 推动制定与维护。
