What SSD Interface has my laptop?

[CesarD]

I would like to know what kind of SSD interface has my laptop.

Here: https://support.hp.com/sg-en/document/c06401081 the brief documentation says "256 GB PCIe® NVMe™ M.2 SSD", but it doesn't specify if, for example, a Samsung SSD with the interface "PCIe Gen 3.0 x4, NVMe 1.3" would fit. Or if the socket allows a "B&M key" connector, or just B or just M.

Thanks!

It clearly says "256 GB PCIe® NVMe™ M.2 SSD" and normally it supports 2280 (80mm) max. It is the first one on the leff

Hi @Banhien.

Thanks for your fast reply, but I'm not sure that answers my question and perhaps I didn't explain myself well enough.

I'm more worried about the keying the socket of my laptop has, in order to know which drives I could plug into it.

The drive this laptop brings from factory is a WD SN520, which uses a B/M keyed connector. Meaning it will be able to be plugged into a B or M keyed socket. 
If this laptop has a B keyed socket, for instance, it could use the WD SN520 I mentioned above, but would be unable to use a drive that comes with only M keyed connector like the Samsung 970 Evo Plus.

Do you know what kind of M.2 socket does this laptop has? Knowing this I should be able to know what drives I could use for it.

Thanks!!
