M.2 NVMe SSD 2T external storage for M1 Mac mini has been added. What is the price and speed difference with the built-in SSD? It’s expensive, but is it fast?

I am thinking of changing the main PC to M1 Mac mini from high performance, power saving, and compactness. However, while it is not extensible, it requires storage for a large number of video files. This time, I added 2T later. Is the 80,000 yen surcharge for the built-in SSD 2T high in terms of performance and price? * Past PC and camera related videos * Tsu-log
