It avoids the need to create LVM or RAID arrays to increase your
storage capacity.
You can add multiple drives to a storage group and mythtv will balance
their usage.
You can manually move files between locations within a storage group
without needing to modify the database.
...
I'm sure they're many more.

without storage groups all recordings have to be within a single
directory.  That can be a symlink to anywhere you want but mythtv
won't follow any nested links to other locations.

When I did it I didn't make any notes which normally means it was easy
enough not to need to.  I think I created a storage group and then
added my existing recording location to it.
