I think that it would be very handy if Dashboard could show drive temperature.
This way users could see which drives are the hottest etc.
By replacing hot drives with cooler ones users could improve their drobos so that they are cooler and thus quieter.
Also I think that those drives that are getting hotter should be placed in the middle where I think the ventilation is better.
I hope it is easy to implement this feature because drobo already monitors drive temperatures.
