A tip here though, copy the DVD/CD from time to time as I have had CDs just die I did not keep them in direct sunlight or anything but I do think they have a shelf life.
I have plenty of hard drive space - that is not a concern.. My computer hard drive is 250 & I have 4 externals with between 120 - 300 Gig each. It is just the time/organization/etc.AND the trying to find things. I would like to have one hard drive just family; one friends' on politics etc.. BUT right now all is spread over all of them & we are talking big projects to do this type of sorting.
I have been motivated to change gears to do work again on some books I started & then put on back burner. Priority changes will have to ensue..
