How Drobo uses your hard drive storage

Are you curious about how your storage is being used? Open
the Drobo Dashboard and click on the triangle next to "How is my
storage being used?" The capacity breakdown bar will appear
showing you how Drobo uses storage.
Available for data: total protected space on Drobo that is
available for you to store data.
Reserved for expansion: unusable capacity reserved for future
use when one hard drive is larger than the others. This space will
become available when you add a larger capacity hard drive or
replace a smaller drive with a larger one.
Used for protection: storage capacity that Drobo uses to protect
your data against drive failure.
Overhead: capacity used by Drobo for management.
You can explore different hard drive combinations using the
Drobolator web tool at www.drobo.com/drobolator.
