This should be using files as disk files, which I did and found it to
be a problem when there is heavy I/O.

Try using LVM then, it allows you to create and resize logical
partitions, including expanding with additional hard disks in the
future without having to reconfigure your VM guest (except the usual
file system expansion steps)

That's my experience too, the more we read, the more
alternatives/options there are, the more confusing it gets! :D
