| Feature | M.2 Revision 3.0 (PCIe 3.0) | M.2 Revision 4.0 (PCIe 4.0) | | | :--- | :--- | :--- | :--- | | Signaling Rate | 8.0 GT/s | 16.0 GT/s | 32.0 GT/s | | x4 Bandwidth (Theoretical) | ~4 GB/s | ~8 GB/s | ~16 GB/s | | Key Features | First mainstream NVMe speed | Consumer SSDs reach ~7,000 MB/s | Data center SSDs reach ~14,000 MB/s | | Ratification Year | 2010 | 2017 | 2019 (PCIe Base) / 2023 (M.2) | | Physical Connector | 67-pin, 0.5mm pitch | 67-pin, 0.5mm pitch | 67-pin, 0.5mm pitch | | Power Delivery | Base standard | Improved | Enhanced |

While maintaining the same connector shape and roughly the same overall dimensions as previous generations, the 5.0 spec focuses on electrical integrity to handle the higher frequency signals without interference. Specification Improvement 32 GT/s (PCIe 5.0) Bandwidth (x4) Connector 75-pin, 0.5mm pitch Voltage Enhanced Power Rails (incl. 0.75V, 1.8V) Keying Retains M-key for NVMe, B-key for SATA/WWAN

Doubled from 16 GT/s (Gigatransfers per second) in PCIe 4.0 to 32 GT/s in PCIe 5.0. Target Industry Applications

Modern gaming engines utilize APIs like Microsoft DirectStorage to stream assets directly from an NVMe SSD to the GPU decompression engine, bypassing the CPU. The massive bandwidth defined in the 5.0 specification virtually eliminates loading screens and enables highly detailed, seamless open-world environments. AI and Data Analytics

Beyond raw speed, Revision 5.0 improves device virtualization and error handling.

A PCIe 5.0 M.2 card can be installed into an older PCIe 4.0 slot; it will operate reliably at PCIe 4.0 bandwidth caps, provided the host motherboard firmware supports the module's protocol. 7. Target Industry Applications
