My internal HD is almost full, so my external 80Gb disk. Mostly filled with iMovie projects and other media files some of which I could archive but I don't want to permanently delete them. Yes I could buy a 120Gb (or even larger) second internal disk - and I probably will - but this would fill up too unless I can archive these somehow, hopefully economically and reliably. What does the list recommend for storage like this? Some of these projects are 20Gb or so. I do have Retrospect (express which came with Norton). -I don't see tape drives advertised or pushed like they used to be. Are these still viable? Do they have OS X compatible drivers? -I do have a SuperDrive - I could use DVD media as file storage, I don't know how this would work but after burning iDVD's (which can take several hours) I'm thinking it would be slow. But the blanks are getting cheap. -Zip drives? Aren't they small capacity and expensive for the blank disks? Any other thoughts? All advice is welcome.
