Hmm... so that's in the order of about 1 €/GB

I wonder if "archival quality" really serves its purpose here.  I mean,
I understand that flash is not reliable in the long term, but there's
also the problem of making sure you'll still have a working DVD reader
in the future.

I thought the only reliable way to archive digital data would be to
treat preservation as a *process*, where you "refresh" your archive
every N years by copying it over to a newer media (with enough
redundancy to detect and correct errors that may have crept in during
those N years).
