Will the Nonvolatile Memory Express (NVMe) and SCSI Express standards increase adoption of PCIe-connected SSDs?
PCIe offers very low latency and high performance, as well as eliminates host bus adapter costs and reduces power consumption. Storage latency has become more important than ever for new applications dealing with big data and supporting data analytics. Getting the most out of solid-state storage to support the real-time needs of these applications is critical. Bypassing the traditional SCSI stack can greatly shorten the I/O path for an I/O request.
NVMe and SCSI Express are aimed at simplifying and standardizing the manufacture of PCIe-connected devices. As consumers see the value of getting the most out of their investment in solid-state storage and pricing continues to drop, we will see an increased adoption of PCIe.
