Yes. Since the storage memory is long-term and rather important if you want to keep program on your app, you must use DmWrite when writing to it. This ensurses that you stay within the memory limits you're supposed to and don't overwrite any other data.
When you read from the storage heap, there's no chance of overwriting data and so you can do this directly. -- Tim Kostka "Marc A.
