The storage monitor could do a stats or history type thing and have a screen with a graph tracking the energy level of the monitored device over time. Perhaps encode the information onto the link card's stack tag in some way, so that it wouldn't lose it or get confused between different storage devices if the card was swapped. Track at several time scales independently to allow for zooming in or out? Not TOO many data points, or it could become a drain on bandwidth / resources...
