M.2 NVMe Device Specifications and Upgrade Requirements for Precision, OptiPlex, Latitude, and XPS Systems

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. An M.2 drive may support SATA or PCIe/NVMe but not both. Depending on the drive, and what the computer can support, not all M.2 drives work in all computers.

M.2 storage devices are classified numerically based on performance. The higher the Class, the faster the overall performance:
