Exactly what the title says, which m.2sata ssd would be the best for the Lenovo Y510p. I want to keep my 750 GB harddrive in there for more storage, and I do not want to remove the second GPU I have so the only option for me is to get a m.2sata ssd. I know that the Lenovo Y510p can be picky with which ones you can and can't use. So which one should I get? I was thinking a Samsung SSD as the seem to be the best in the m.2 form factor. Also where would I get the screw for the m.2sata SSD?
