The vertical output makes it quite difficult to spot unbalanced drives
tough.
A simplified output might help:
Just show how much is used/unused on each drive. This helps the usecase to
spot unbalanced drives, I think. And it can fit in tabular output.
I think its good to go from the use cases. What questions may the user
have and how to answer them in a clear and concise way?
Then for details the vertical output might be a good option.
Anyway, I think first go for the summary thing… since I think that is
clear.
