A PCIe SSD refers to a solid-state drive that uses the PCI Express (PCIe) interface for data transfer, offering faster speeds than traditional SATA SSDs. NVMe SSDs, on the other hand, use the NVMe (Non-Volatile Memory Express) protocol over the PCIe interface, providing even faster performance and lower latency by optimizing communication between the storage and the CPU. In short, all NVMe SSDs use PCIe, but not all PCIe SSDs necessarily use the NVMe protocol.
