A:Answer I just replaced SSD to 512GB by cloning.
Right after I installed larger SSD, it was slower than my older SSD, but after few days w/ few restarts, it came back to normal speed.
From my experience, it was okay to clone old SSD to new SSD.
But make sure you buy correct "NVMe enclosure" (not NGFF, it will not fit) to clone SSD properly.
