>> Am I missing something here or is there a way to make better use of RAID?
RAID 1 protects against a disk breaking down, that's all. Different other versions perform different functions, of course.

>> huge cluster of RAID 5 drives
Some do, but only very big outfits. Most rely on a good backup system. Some of the enterprise grade backup products are phenomenal.

>>I understand that if one drive has bad sectors then the corrupt data will simply be mirrored to the other one
That's not how it's supposed to work. When it develops bad sectors it warns you and you then call upon your redundancy to replace the faulty drive.

>> Is there another solution in a single system to remove/reduce the risk of data corruption with RAID-1?
There's the less talked about Matrix RAID - provided you have the right hardware - but, I'm afraid, it's probably not what you're looking for. You could have a third hard disk and regularly Ghost/DriveImage to this drive either manually or automatically.
