Being mobile I am space challenged so I just use old hand me down Laptops. They all have disks except one ASUS which is a hybrid drive hard/SSD. But all my USB drives are SSD. That is the cool thing about Linux, as you know it likes old computers so acquiring give away Laptops is easy. I just keep the disk drives backed up well in case they fail.
In many ways you are lucky to have culled your possessions to what you can keep with you. I have collected so much crap that it is difficult even to find another house with garages and shops that could accommodate all of my stuff. It ties one down.
