How did you "find" that?
I ask because I haven't had a single backup drive failure since DVD burners became affordable. And, as discussed before, I often use fairly old second-hand drives. I used to have drive failures with really old drives (too small to be useful nowadays) but all the drives failures I've witnessed in the last few years have been workstation/laptop/server drives.
If DVDs indeed lasted longer, I could have a use for them. I wouldn't be surprised but I don't have enough experience with DVDs to know for sure. It's what I have read that scared me... specifically, that burned DVDs, like burned CDs, tend to slowly develop small errors. I've certainly experienced this with CDs. OTOH, backup hard drives tend to fail totally and without warning (well, the old ones that failed me years ago did that anyway) which is a good thing because then you know they're broken. With DVDs, you'd have to read the whole content and checksum it from time to time to make sure that all the data's still there if you want to use them for long-term storage. I guess it's also good practice to do that with hard drives but it'd be a lot faster if you've got hundreds of GBs that you want to store for the long haul, isn't it? Or maybe I'm missing something?
