I'm considering whether I really want wallets and wallets of DVDs for
backup - DVDs which may not be readable in a few years time. Instead, I'm
thinking of a couple of portable 250GB 2.5-inch HDs......

A highly risky approach. One head crash and you lose everything.

Besides it's sufficient if DVDs last until the next generation of media
becomes available. You then just need to copy all your disks to the next
media generation.
