I wrote about my experiences with the native NVMe driver last October. This driver works, but does not offer the best performance. Windows Server 2012 R2 and Windows 8.1 have a native NVMe driver that allows NVMe devices to be automatically recognized by Windows. NVMe is being pushed as a modern replacement for the old Advanced Host Controller Interface (AHCI) that most flash storage devices are still using, and all indications are that NVMe will really start to become more popular and more affordable in 2015/2016. NVM Express provides a standards-based approach enabling broad ecosystem adoption and PCIe SSD interoperability.” NVM Express significantly improves both random and sequential performance by reducing latency, enabling high levels of parallelism, and streamlining the command set while providing support for security, end-to-end data protection, and other Client and Enterprise features users need.
“NVM Express is architected from the ground up for Non-Volatile Memory (NVM). Even though this technology is most relevant for server workloads, there are also some affordable new NVMe devices meant for client devices and workloads. It gives lower storage latency and much higher queue depths.
