If you are archiving then there is a difference between CD and DVD

I suspect there's less difference between those than between
brands/qualities of CD media, but I haven't checked the literature
recently. (They shouldn't be _that_ different if a single drive can
happily burn both...?)

DVDs are certainly more convenient since they're higher density. On the
other hand, increased density does mean increases vulnerability to a
Small Random Event unless the ECC has also been beefed up...
