Differentiating M.2 SATA from PCIe

I'm looking to add an M.2 SSD to my laptop but I don't know if the M.2 slot supports SATA or PCIe. Is there any way to know other than buying and testing?
Laptop is an Acer E14 E5-475G. I can't find anything about this on their website.
Thanks in advance, forum.

    Sorry, but the article doesn't really say how to know if the slot connects through PCIe or SATA.
    The article mentions "So if you try to use a PCI-E drive in a SATA-only M.2 slot (or vice-versa) it will not function correctly." which is essentially my question, how do I know if the M.2 slot on my laptop's board is SATA-only or PCIe-only or if it supports both?
    Or did I miss anything from the article?

  2. Hi

    are you sure there is a M2 slot on the motherboard?

    I looked at the Crucial memory site and they offer DDR4 SO dimms and standard 2.5" sata SSD with no M2 drives offered

    EDIT I was wrong Crucial does not seem to be offering M2 SSD's
    I found one link suggesting M2 SSD for that laptop

    Yep. It has an M.2 slot. If the guy in the vid got an 850 EVO working, can I assume my laptop takes SATA M.2?

    There is M key and B Key. M Key only is a PCIe Deivce a M + B Key is a SATA Device. If you look at your interface on your board and you see a notch ONLY for the M Key it will do both. If you see a notch for BOTH the M + B Key then it a SATA Only slot. Again this is looking at the board NOT the SSD Drive itself as a NVMe will be M key only while a SATA Device will have both but it all depends on what the motherboard is showing.

  5. Your Acer laptop will only have a m.2 SATA connection because it is a rather inexpensive laptop. M.2 PCIe NVME are basically found in more expensive laptops. Generally speaking, I would say they can be found in laptops that are equivalent to $1,100+ USD laptops.

  6. Why don't you contact Acer tech support at https://www.acer.com/ac/en/MY/content/support and obtain a definitive answer to your question?

    Have handy your laptop's model #, serial #, and the PRECISE make/model of the M.2 SSD you're possibly planning to purchase.
