Thank you for your insightful explanation getit29! So, would you recommend this Verbatim UltraLife Archival Grade DVD-Rs/CD-Rs for storing very important data? I'm choosing this because of its metal AZO dye and dual layer technology (part silver, part gold).
On a different note, I notice that one of your burners is NEC/Optiarc brand. I have a Sony NEC Optiarc AD-7230S DVD+/-RW burner, which came with my Dell XPS 730X system. Since you seem experienced with and knowledgeable about burning and testing burned discs--which is hinted by your six burners--I would like to ask you your recommended burning speed for my AD-7230S drive? I've read from other posts that to always burn at half the rated speed, which in the case of UltraLife 8x DVD-R is 4x. Does this also apply to UltraLife 52x CD-Rs? I also read that the standard scanning speed for NEC/Optiarc drives is 5x.
