I don't know about solid-state devices. But I think if I can make a safe write on a DVD-R (comparing the checksum) probably I won't have to worry about the media for one or two years. Using a disk... If something is wrong with the electronic device, my read after two years can destroy everything in one single step. Of course If I have a laser problem on DVD device... but have you ever noticed about a laser problem that had destroyed an -> already <- written DVD media when you just want to -> read <- data? I think DVDs is really reliable to keep data readable (one or two years, wherever), but not to write. And disks is more reliable to write and not to read. Of course what I'm saying is about a -> crash <- at the restore moment, not a misunderstood byte or something. Normally I have to scratch a DVD-R on the wall or write wrong data to destroy my day at a restore moment. If I use a disk... I think it will always be a stressed restore moment. DVD-R just seems to be like a piece of paper, extremely fragile, but extremely simple. But, of course, I'm not a specialist, I don't know if a solid-state is more simple than a burned piece of plastic. I'm really enjoying this discussion. I hope I'm not insisting on a redundant discussion. Sorry if it's the case.
