M.2 form factor

The M.2 is just a form factor port for different kinds of computer interfaces. The implementation of the interface will depend on the hardware. There are mainboards that support M.2 for SATA, other for NVMe (PCI Express, PCIe) and some other support both.

SATA

There are reports of having an M.2 SATA SSD drives working on OS/2 Warp and ArcaOS.

The WD Blue 3D NAND SATA SDD M.2 2280 (1TB) was reported to be working on a ThinkPad 25. It works connected to the M.2 NVMe port, but please remember that not all M.2 NVMe ports have SATA compatibility.

NVMe

NVMe was released by Arca Noae for SSD devices on OS/2 in April 2021. The intentions of developing a driver from Arca Noae had been shared at Warpstock Europe 2019, and a driver had been produced by Arca Noae. [1].

Some M.2 NVMe have SATA compatibility, so an M.2 SATA card can be connected and will work on OS/2, but it is not common for all NVMe adapters.
