PCIe NVMe SSDs can provide much higher performance than standard SSDs through their use of the non-volatile memory express (NVMe) protocol and the peripheral component interconnect express (PCIe) interface, rather than the SATA/ACHI interface used for disk drives and SSDs over the past decade or so. With a higher throughput and lower latency, NVMe SSDs can accelerate PC workloads as well as servers. However, testing and benchmarking SSDs for use in PCs is substantially different than for servers. The input/output characteristics of PCs tend to not have deep queue depths, and also use a large variety of packet sizes. Thus, using standard server benchmarking tools and configurations can result in skewed benchmarking results.
