Either digital ocean actually has real SSd disks for each vm or something is deeply wrong. A new VM should have a new disk file. When I create a vm I create a vmdk file that represents the disk. When I delete the vm I also delete the vmdk file. If I then create a new vm I would use a new vmdk file. Apparently that is not the way digital ocean does things, but how do they do stuff then?
