What is a NVMe (Non-Volatile Memory) disk (NVM/PCI protocol)?

About

The original SATA protocol was designed to maximize the performance of platter (physical spinning) hard drives.

With the proliferation of SSD drives, the SATA storage management protocol has become a limiting factor.

The NVMe (Non-Volatile Memory) protocol:

• has been designed for solid state drives
• and uses the PCIe bus for optimal performance.

Drive Supporting Nvm

PCI Generation

PCIe is a standard interface for connecting high-speed peripheral components to computer motherboards.

• PCIe 4.0 standard (ie 4X), was announced in 2017.
• PCIe Gen 4 doubles the data rate of PCIe Gen 3, allowing PCIe Gen 4 devices to transfer data at much faster speeds.
