I'm currently using EXT4.  CentOS 7 doesn't support ZFS and I've been
watching BTRFS for years now and it just never seems ready for general
production use, so EXT4 seemed like a good fit for a backup drive.

Yes, I had considered that it might not be the drive or cable (I've already
replaced the cable too), but rather something on the motherboard.

Do these suggestions imply that the only reasonable answer is that I do
have a hardware problem?

I might try BTRFS on this particular backup drive, just to see what
happens.  Thanks for the suggestion.
