[Help] NVME, SSD, Harddrive issues

[oSecret]

So I recently purchased a new SSD to add to my system to replace both of the HDD's I have, it worked fine until I started putting stuff on the drive then I kept getting "a device which does not exist was specified" which I'm guessing is due to it disconnecting? I cannot figure out whether I am at my limit of lanes or whether this SSD is just faulty, any help would be greatly appreciated. I have 4 Sata slots so had to remove a drive to add the new one, was going to transfer all the data from my 2 HDD's then plug the SSD I removed back in.

-Something to add, this new drive doesn't show up in Samsung Magician

I think it might be a fake? All my other drives come up with their names, this is just called SSD
