Thanks. It is verified that the SPIN 3 has a m.2 "M" key connector. what type of m.2 ssd I should get? msata or PCIe NVMe type? It appears all the PCIe SSD is "M" key.
Does it support boot from PCIe? Where I can find information about the motherboard? Enter to the BIOS doest seems to be UEFI boot.
The SPIN 3 with HDD is painfully slow and not responsive. What's the reason to sell a i7, 12G DDR4 RAM with crappy HDD to make it like a sub $300 PC while I paid $600 for it!
