nonvolatile memory express

Nonvolatile memory express (NVMe) is a high-performance, scalable host controller interface designed for accessing solid-state storage devices, such as solid-state drives (SSDs), to leverage the speed and parallelism of PCI Express (PCIe) technology. NVMe is optimized for low-latency, high-bandwidth, and parallel access to flash-based storage, offering significant improvements over older interfaces like SATA (Serial ATA) that were originally designed for hard disk drives (HDDs).

Key features of NVMe include:

Low latency: NVMe reduces communication overhead and latency, maximizing the performance potential of SSDs.

High bandwidth: Takes advantage of PCIe's high-speed data transfer capabilities, allowing for faster data throughput compared to SATA.

Parallelism: Supports multiple queues and commands simultaneously, enabling efficient handling of I/O operations in parallel.

Scalability: Designed to scale with advancements in SSD technology, supporting future generations of storage devices.

NVMe has become the standard interface for high-performance SSDs in both consumer and enterprise environments, offering superior speed and efficiency for applications that require rapid data access and processing.
