Official, legally compliant copies of the PDF are distributed directly by the PCI-SIG . While member companies receive complimentary access to incorporate the standards into their commercial products, non-members typically must purchase the document directly from the PCI-SIG specifications library. Summary of Specifications PCIe M.2 Rev 4.0 PCIe M.2 Rev 5.0 (Ver 1.0) Gigatransfers per Second Max x4 Throughput Encoding Overhead 1.5% (128b/130b) 1.5% (128b/130b) Primary Use Cases High-end PCs, PS5 AI workstations, Next-gen servers, Enthusiast PCs
Real-world deployments, like the or high-end Phison-driven modules, translate these raw layer specifications into sequential read speeds pushing past 14,900 MB/s and sequential write speeds hitting 13,800 MB/s . This enables immediate data delivery to high-compute applications, real-time AI modeling, 8K video timelines, and DirectStorage-optimized gaming engines. 2.

The PCI Express M.2 specification is not a standalone creation; it is an to the core PCI Express Base Specification. Revision 5.0 of the base spec doubled the data rate from 16 GT/s (PCIe 4.0) to 32 GT/s per lane. However, translating that raw speed into the compact, card-edge M.2 form factor required a dedicated revision.
Beyond raw speed, Revision 5.0 improves device virtualization and error handling. Beyond raw speed
| Feature | M.2 Spec Rev 4.0 | M.2 Spec Rev 5.0 V1.0 | | :--- | :--- | :--- | | Max Link Speed | 16 GT/s (PCIe 4.0) | 32 GT/s (PCIe 5.0) | | Max Power (without aux) | 7.5W (typical) | 11.5W (extended to 14W with thermal solution) | | Heatsink definition | Optional, no standard | Mandatory reference design | | Keying for PCIe x4 | M-key or B+M | M-key only | | Low-power idle | L1 substates (vague) | L1.1/L1.2 (defined timings) |
: To manage the challenges of 32 GT/s speeds, the spec includes updated high-speed differential AC coupling capacitor values and refined connector requirements to minimize channel loss. Form Factor and Compatibility
