I just updated my SSD setup in my laptop recently.
I’m vaguely amused the Thunderbolt 3 external SSD is 5x faster than the internal SATA connected one.
Originally I went from a 512GB manufacturer SSD to a Samsung 2TB for Windows. The move went fine. I couldn’t successfully clone to go from the 2TB to the 8TB though. Had to disable Intel Optane caching in the EFI and re-install Windows.
