Hi I have a 1TB Samsung 970 Evo Plus. I contacted my Local IT Group who installed these SSDs and apparently the cost of a full data transfer to a 2TB version of it would cost me about £300 which I do not have spare to spend. Still there will be some storage left but under 50GB for sure. If I do "fill up" my current 1TB SSD should I expect performance losses and if so by how much?
