Well, I'd go with the external harddrive...mainly because I don't have to go looking for a disc when I need anything, and everything is in one place.... It will be more dependable, because discs may suddenly go kaput at any time, and yes, their lifespan is likely to be longer than discs. So I vote for the HDD.
I can't think of a single "benefit" to utilising CDs. Yes, they are inexpensive, but they take up so much more room and are so readily scratchable that the "positive" is rendered meaningless. Thank you for visiting our Tech site
