No matter what type of archive you use, be it tape, external drive,
online storage, offline internal drives or cd/DVD, it's imperative to
have redundancy and test your backups routinely. Any large company
does this. Also, never store both copies in the same location. A
house fire is terrible, but you wouldn't want to lose both copies at
once.
I'm in the process of setting up a mirrored raid setup over a VPN, and
while my offsite storage isn't ideal for a true disaster due to
distance, I feel I'm reasonably protected. You ideally want 50 miles
separation for disaster recovery site and I'm at about 15
Anyway, you can easily mix and match media, copy on an external drive
and also on an internal. Or external and DVD
A backup is only as good as your last tested restore. Nothing is
worse than trying to restore some lost data and your backup drive
fails, or the cd isn't readable. It's important to test your backups
routinely.

I have a $150 100GB ext. HD paperweight with a bunch of data that is

Why archive data on CDs or DVDs at all? Why not use external hard
disk drives instead?
