Well, James asked for advice on USB disk drive that will be used as
storage for backups.
It may seem like overkill, but I would prefer to be sure that my backups
are safe and consistent, because there are many ways things could go wrong.

Speaking of RAID in general, I can see usefulness of URL you provided,
but only as a guide to fight with "I have RAID, it works, so I can
forget about it" kind of mentality of inexperienced people.
Yes, backup is important, but it is also important to be sure that your
backup will not fail you when you will need it the most, so using RAID
with proper monitoring and servicing procedures is always better than
just one drive.
