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.

PCI Express M.2 Specification Revision 5.0, Version 1.0 Release Date: May 2021 Publishing Body: PCI-SIG (Peripheral Component Interconnect Special Interest Group)

to handle higher power demands for performance-oriented modules. Voltage Support : Added support for 0.75 V core voltage in the PWR_3 rail specifically for LGA Enhancements : Introduced support for for Land Grid Array (LGA) modules. Errata Corrections : Incorporated critical fixes from the November 30, 2022, errata table (v0.7) and the August 17, 2022, errata Hold Time Reductions : Included reductions for asserted hold time to optimize power state transitions. Specification Structure

~16 GB/s over the same x4 M.2 slot configuration.

Because the PCI-SIG is a member-driven consortium, official specification PDFs are tightly controlled to ensure intellectual property protection and engineering accuracy.

The M.2 (Next Generation Form Factor, or NGFF) standard has come a long way. It was designed as a compact, versatile replacement for older standards like mSATA and Mini PCIe. Over the years, the spec has evolved to keep pace with the ever-increasing demands for data throughput:
