CD-R should last much longer than DVD-R.
I bought a BD-R drive and discs with the idea of long term backup. Wrote 3
copies of stuff to some discs, and put them on a shelf in dark and nice
temp and in cases. 7 months later none of the data was readable :-(
Memorex discs which are rebranded some other company. Wasn't impressed.
I used to run a site called Dustbunny, planning to bring it back. Can't
wait for the 8TB seagates next early next year.
