Have peered inside my miniature PC ahead of its #Ubuntu augmentation. It only has one M.2 slot for its #Windows 500GB SSD so the new drive will have to use a spare SATA bus. Partly to save money, partly because it’s just an experiment but mostly so I can distinguish the new drive from the old one, I’ve ordered a Samsung 250GB SSD. (I was also keen not to buy American, of course.) Next step will be preparing installation media for both OSes (in case something bad happens to the Windows 11 drive).
