Problem with backup volumes

I started seeing bad blocks from the external Seagate SSDs that I was using for backups so I bought Western Digital spinning-disk drives instead and new cables and moved to using those. They too worked fine for a while but now I am starting to see unreadable disk sectors again.

I guess that I can't rule out some issue with the OpenBSD Intel Wildcat xHCI driver; the relevant computer will soon be shifting to NetBSD. Though, I think that I managed to reproduce the bad sectors from the Seagate drives on my Linux laptop. I am trying one of the suspect Western Digital drives on a NetBSD computer next.

I want removable drives because transport by car remains a great way to arrange off-site backups. I am wondering what my next move should be but I should not procrastinate as unreliable backup volumes are intolerable.
