NVM Express – The Optimized PCI Express* SSD Interface

The NVM Express specification, developed cooperatively by more than 80 companies from across the industry, was released on March 1, 2011 by the NVMHCI Work Group; now more commonly known as the NVMe Work Group. The NVM Express 1.0 specification defines an optimized register interface, command set and feature set for PCI Express* Solid-State Drives (SSDs). The goal is to help enable the broad adoption of solid-state drives (SSDs) using the PCI Express (PCIe) interface. For more information visit www.nvmexpress.org.

Prior Specification Revision

The NVMHCI Workgroup released the NVMHCI 1.0 specification in 2008, which was focused on client caching applications and included a close relationship with the Serial ATA AHCI interface. It is recommended that the NVM Express interface be used rather than the original NVMHCI 1.0 specification for new designs.
