Which gives me an idea on where such a thing might be useful - RAID |
14 |
|
15 |
If SMART (or something conceptually similar) detects that a drive might |
16 |
be failing and be beyond the range of the drive's ability to cope, it |
17 |
could raise an event and move the blocks used to another disk. This |
18 |
could give another level of data protection rather than just simply |
19 |
relying on multiple copies as current RAID schemes mostly do |
