The PCI Express (PCIe) M.2 Specification Revision 5.0, Version 1.0 defines electro-mechanical standards supporting 32 GT/s data rates, doubling bandwidth to approximately 16 GB/s for x4 NVMe SSDs. It introduces critical updates including a 0.75V core voltage rail, 1.8V I/O for LGA modules, and enhanced amperage handling, while maintaining full backward compatibility. Members of PCI-SIG can access the full technical specification at PCI-SIG Specifications Library . PCI Express M.2 Specification Revision 5.0, Version 1.0 It introduces critical updates including a 0
Released by the PCI-SIG (Peripheral Component Interconnect Special Interest Group), this document is not merely an incremental update. It is the architectural blueprint that enables M.2 SSDs to leap from 16 GB/s (PCIe 5.0 x4 theoretical max) to the raw physical limits of the new signaling standard. For engineers, procurement specialists, and hardware enthusiasts, understanding this 1.0 version of the M.2 specification is critical to designing compatible, high-performance systems.
