Many consumer SSDs with NVMe support are already available or will be available soon.

Nearly all mainboard manufacturers are meanwhile offering new BIOS versions with full NVMe support for their mainboards with an Intel 9-Series or X99 Chipset.

For Win7 and Server 2008 R2 users I recommend to read the start post of >this< thread.

The latest Windows Operating Systems from Win8.1 up natively do support NVMe.The table below summarizes high-level differences between the basic NVMe and AHCI device interfaces:Įverything seems to be prepared for a drastical SSD performance boost by the new data transfer standard named NVMe: At a high level, the basic advantages of NVMe over AHCI relate to its ability to exploit parallelism in host hardware and software, manifested by differences in depth of command queues, interrupts processing, the number of uncacheable register accesses etc., resulting in various performance improvements. NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and fulfilling the parallelism of contemporary CPUs, platforms and applications. Such an interface has some inherent inefficiencies when applied to SSD devices, which behave much more like DRAM than like spinning media.

This is because AHCI was developed back at the time when the purpose of a host bus adapter (HBA) in a system was to connect the CPU/memory subsystem with a much slower storage subsystem based on rotating magnetic media. While Advanced Host Controller Interface (AHCI) interface has the benefit of legacy software compatibility, it does not deliver optimal performance when an SSD is connected via PCI Express bus. “NVM” stands as an acronym for “Non-Volatile Memory”, which is used in SSDs.

NVMe is a specification for accessing Solid-State Drives (SSDs), which are attached through the PCI Express (PCIe) bus.
