The (officially titled "PCI Express M.2 Specification Rev 5.0, Version 1.0" ) was released in late 2024 and marked as "updated" in Q1 2025 with several errata and clarifying annexes. This article reflects that updated content. , which doubles data transfer rates and introduces

Prior to this release, most M.2 implementations were based on the M.2 v1.0 specification (released around 2013-2016), which was retrofitted to support PCIe 3.0 and later 4.0. Prior to this release, most M

The official document was released by PCI-SIG on . This specific date is significant as it marks the point when the specification transitioned from engineering draft to a fully ratified industry standard. Over the years, the M

Over the years, the M.2 specification has evolved in lockstep with the PCIe Base Specification. The journey from M.2 Revision 3.0 (aligning with PCIe 3.0 at 8 GT/s) to Revision 4.0 (16 GT/s), and now to Revision 5.0 (32 GT/s), reflects the industry's relentless demand for faster data movement. This evolution is also reflected in the mechanical design of M.2 sockets themselves, with Gen 5 sockets maintaining the same 67-pin configuration and 0.5 mm pitch while supporting much higher signaling rates.
