NVMe SSDs (e.g., Samsung 980 Pro, WD Black SN850) that use PCIe lanes, or legacy PCIe SSD cards from brands like Fusion-io or Intel Optane (when based on flash).
Here are the proper features related to PCI Flash Memory, categorized by Physical, Protocol, and Performance characteristics: pci flash memory

Traditional storage interfaces process data sequentially through a controller hub. In contrast, PCI flash devices use a point-to-point architecture. The interface maps directly to the motherboard via individual data pathways called . Each lane ( The interface maps directly to the motherboard via
After months of development, the team finally had a working prototype. They inserted the PCI Flash Memory module into a test computer and held their breath as they ran the first benchmarks. The results were astonishing: the module was delivering sequential read and write speeds of over 1 GB/s, far outpacing any existing storage solution.
The proper feature that distinguishes "PCI Flash Memory" from standard SSDs is the . By utilizing the PCIe bus and the NVMe protocol , the storage media communicates directly with the system CPU and Memory, unlocking bandwidth and latency performance far beyond legacy interfaces.
