There is a particular notion of "radix economy" which takes into account both the length of a number compared to its size and the informational complexity of more symbols. It doesn't really have anything to do with data storage though. If you could create a device to store 1000 10-bits (10its?) for exactly the same cost as one that stores 1000 3-bits you'd obviously pick the base 10 one, no matter what radix economy says.
