I'm interested in experiences of others. In my experience CDs and DVDs
more likely will fail, than HDDs do.
How should DVDs and CDs be stored? I guess UV light will harm them, not
an issue, they simply should be stored in a drawer.
Regarding to my experiences and the experiences of friends with CDs,
DVDs, DVDRAMs, USB sticks, DAT tapes, HDDs (from different ages) and
floppy disks and the experiences regarding to SyQuests from friends
- CDs, DVDs, USB sticks, DAT tapes (equal to those small computer data
cassette tapes) are completely unreliable
- HDDs are relatively reliable
- Try to get a SyQuest drive in 20 years
- Using DVDRAM is something between a PITA and impossible, they are at
least usually very slow on Linux
That's why I bought an USB HDD awhile ago.
