Simple answer. None of these discs have been around as long as the HDD so
how is anyone able to do anything but speculate? I have hard drives that are
older than any disk format that still have accessible data. I would say
without a doubt that at this time HDDs will outlast any disk if they are
treated properly in the realm of archiving. Store disks without using them
and they may decay just sitting there. If discs are rotting already then
what does that say about them. Store HDDs in the same manner without having
them powered up and I say they are a better answer then just the disc alone.
