How does "Disk Space Used This Month" work?

Hi, I started my Storj node yesterday, and had a question about what this metric means. My node has about 3.5GB of data in it, but the “Disk Space Used This Month” is showing 11.04GBh. What is "GBh" and does it correlate with the amount of data being written to the disk?
