The secondary DNS is important because the primary from time has to reload
its database. During that time it wont answer any queries. So the sondary
will play it role for that short time.

The same goes for the secondary when it updates its database from the
primary.

When running, bind does not use the disk at all. Only for logging,
loading and updating you need a disk. I have seen bind running from
ram disk or flash.
