Disk usage is represented by two bars: one for the used space and one for the free space. Their sum is always 100 %.
In my opinion, there is no useful information in a second bar, neither is in the color change.
Solution:
Instead, use only one bar that represents 100 % by it's length and mark the disk's usage, i.e. as in the attachment.
This could save a lot of space (1 row instead of 3 or 4) and prevent from redundancy.
