Why? Because higher test scores translate into greater “knowledge capital” — that is, the full body of knowledge available to an economy — and boost economic growth (and, incidentally, the tax revenues that fund our schools).
Ah yes, the only reason to ever do anything: line go up. Not like formative education has any other value.
There’s a few ways to go, I have used dd in the past to clone the existing drive out to a disk image on a USB SSD, then installed the new SSD in the system and did the process in reverse (and then used gparted to expand the partitions out to size).
There’s also cloning devices that can do this but I’ve only ever done that with traditional 3.5" and 2.5" disks, not m.2.
Whatever you do, make sure you have a backup of your important data before you make any attempt.
I would also like to know how you did that because as far as I’m aware Fairphone is not supported.
