RAID-5 tolerates only one HD failture and no HD error!

The RAID-level you are looking for is RAID-6, that means, you have two
spares. A RAIS-6 Array can correct an HD error and can tolerant up to
two defect HDs. These controllers are very expensive.

You can own a controller like this for example from MYLEX. If you want
to buy a New Computer I suggest looking for a HP NetServer: the build-in
Controllers support RAID-6, too.
