I don't know of any disadvantages to having it enabled. But you
shouldn't need to enable it in rc.local; turning on SMART is supposed
to be persistent (at least according to atactl(8)). That said, I think
I have some drives where it isn't persistent, and as a result I don't
trust their long-term SMART data-tracking.
