You can make a single disk dynamic. So where's that info stored then?

You can still import a drive even without previous knowledge of the
drive, there are just a couple extra steps.

Each and every dynamic disk has enough information to understand the
structure and to allow Windows to figure out which volumes belong to
which set even if the disks are moved to another computer in the wrong
order.

In addition, the layout data is stored in the registry, but you most
definitely can move dynamic disks to new machines, import them and gain
access to the data.

Each disk contains *all* info. It's not on another disk, it is not 'just'
enough, each disk contains a complete LDM database.
