Increased data on the hard drive won't really have an affect on
reliability or performance.

I can't speak directly to the asterisk + openfire situation. I can,
however, say that I've been running openfire for nearly a year now on
a very highly-loaded server (other than openfire, it's running nagios
and cacti, monitoring about 300 devices around our network) - the load
average on this 5-year single processor old dell server is pegged near
1.00 24x7. I haven't had a single problem with openfire, and I have
between 50 and 100 open sessions at any one time. In the year that
I've been running openfire, I've only had to restart it once, and that
was to upgrade the software. It takes very little CPU, and a modest
amount of RAM.

What's your definition of "better". Is it better to not have all your
eggs in one basket? Is it better to only need to purchase one server?
Is it better to only have one server to manage/update/etc versus two?

Speaking personally, I'd have no problems putting openfire and
asterisk on the same box. If needed, you could even just "nice" the
openfire process down to a lower priority than asterisk - it's not as
latency-sensitive as asterisk is. I'd doubt you'll need to do that,
though.
