Ahh I understand more clearly now. Because the failing drive will
report an IO error the raid system can respond reactively by getting the
data else where and writing it to the failing disk. Earlier I had
thought that the raid system might periodically poll the disks to see
what blocks were lost and correct them.
This makes me much more interested in setting up a raid system above and
beyond the performance benefit.
