I’m posting this because I got a remarkable speedup from the firmware upgrade and I’m also pretty happy that the upgrade went that well.
NVMe drives’ firmware is writable?!
I wonder if that could also be made part of LVFS (fwupd)? They do support BIOS updates for this model: https://fwupd.org/lvfs/device/798ffd60-f10e-4ac4-8939-c8beabfe55b4 or is an SSD firmware update just too risky for automating this?
