My SSD is running out of space in my machine and I thought rather than just put in a larger one I would take advantage of the M.2 connector in the MB.

The MB is this one  https://www.gigabyte.com/Motherboard/GA-A320M-S2H-rev-1x/sp#sp

The documentation says the M.2 socket is as follows

1 x M.2 connector (Socket 3, M key, type 2242/2260/2280/22110 SATA and PCIe x4/x2* SSD support)
* Actual support may vary by CPU.
* Supports only M.2 SATA SSDs when using an AMD Athlon™ 200-series/ 7th Generation A-series or Athlon™ APU.

The current processor in the MB is an AMD Ryzen 3 2200G

I am new to this are but this does mean I can put in something like this?
