Which interface does NVMe (Non-Volatile Memory Express) utilize?

The selection of the M.2 interface is accurate because NVMe is designed to take advantage of the high-speed capabilities provided by this interface. M.2 allows for a significant increase in bandwidth compared to older interfaces, especially when connecting SSDs (Solid State Drives) that utilize NVMe technology.

NVMe communicates with the system via the PCI Express (PCIe) bus architecture, which enables it to achieve faster data transfer rates and lower latency. While M.2 connectors are often used for NVMe drives, it's important to understand that M.2 can also support SATA drives. However, the defining characteristic of NVMe is its specialized capability to utilize the M.2 interface for optimal performance.

The SATA interface, while traditionally used for SSDs and HDDs, doesn't support the NVMe protocol. Similarly, USB interfaces are not designed for direct internal drive connections and do not utilize NVMe capabilities for storage solutions. Therefore, while PCI Express is integral to NVMe, the M.2 interface specifically encapsulates the form factor widely associated with NVMe SSDs.
