I did try that once but didn't manage to do it, the kernel upgrade broke
other stuff. I'm a bit more experienced then complete newbie (hence
using btrfs), but still very far from knowledable user, so I don't doubt
it can be done. Indeed, using btrfs might be seen as a wrong move in my
case, which I understand, although on the other hand btrfs saved me many
times from other begginer mistakes by allowing a simple restore by just
renaming snapshots.

Ok, I've been warned then. I'm glad to know about the samsung EVO
though, I've been eyeing buying two of those for a raid1 system. Then I
would solve two issues in one go !
