Request for opinions - gvinum or ccd?

There is one last thing I'd like clarified. From the zpool
manpage:

  In order  to take advantage of these features, a pool must make use of
  some form of redundancy, using either mirrored or raidz  groups.  While
  ZFS  supports running in a non-redundant configuration, where each root
  vdev is simply a disk or file, this is strongly discouraged.  A  single
  case of bit corruption can render some or all of your data unavailable.

Is this supposed to mean:

  "ZFS is more fragile than most. If you don't use redundancy, one
   case of bit corruption will destroy the filesystem"

Or:

  "Hard disks explode often. Use redundancy."
