I just had a second Samsung 980 PRO start dying, and had several more in my homelab cluster, so I was dreading doing this on my desktop computer (I have a small form factor), but it was a breeze on the framework.

I used a gparted liveUSB with the firmware on it (the tool is actually just a x86_64 binary), unscrewed the back screws (the captive screws makes it so I don't even need a screw tray), then took off the keyboard, and popped in the SSD, pop the keyboard back in its magnet and go and upgrade.

The brilliant part is that the keyboard is attached by magnets, and is easy to pop on and off to replace the SSDs, and before I knew it, all 5 SSDs were upgraded.
