> If I were one to use a laptop - which I most certainly do not - I think that's why you don't consider it unthinkable to carry around such a thing along with your laptop.
What you're suggesting looks like the following to me: - I go to my favorite café to work for the afternoon [ ah, the good ol' days before covid! ] - I take out my laptop - I start to wo.... oh no, wait, I forgot, I also have to: - take out my RAID disk - plug it in - notice that it needs power - take out its power adapter - look around to see where on earth I'm going to plug it - wonder why I bother carrying a laptop with a battery if my drive needs a power outlet > I wouldn't carry the array around, however. It would sit either at > home or at work (one and the same, for me) and I would access it > through the internet. So we're back at square one: your laptop wouldn't have a RAID drive and neither your root partition nor your $HOME files would be protected by RAID. I'm glad we agree ;-0 BTW, if you care about RAID and about having a laptop, there are many good options out there for laptops that can take two internal drives (either 2x 2½" or 2x M.2 or a mix of the two).
