Hello,
for the Samsung SSD 870 QVO SATA III 2.5 inch your laptop needs a SATA interface as well as a free mounting slot in the form factor 2.5 inch.
This should be available on your Macbook.
If in doubt, please contact Apple support directly.
Kind regards from Schwalbach,
Your Samsung Service Team

This works instead of the system disk. First clone the system to an external disk, then rebuild the SSD or copy it back. Watch the corresponding Youtubes for the installation...

Good day
To be honest, I don't know.
