There are different sorts of RAID arrays, but the concept of true RAID is that, if a disk fails, the rest of the multi-disk system contains the wherewithal to reconstruct the contents of the failed disk on the replacement. In effect, the array repairs itself. This reconstruction is of the whole data structure, rather than of individual files, and it tends to take a long time, which is a significant disadvantage. For a fuller and more technical description, see this Wikipedia article.

This is true for a drive hardware failure but cannot protect against any other causes of file corruption such as software problems or human error.
