Calculating Capacity To Use - Drobo 5N2 User Manual

1.7.1 Calculating Capacity to Use

The best way to determine how much usable, protected storage space you will have available for
your data, based on the number and capacity of the drives you use in your Drobo device, is to use
our Capacity Calculator at www.drobo.com/calculator.
A shortcut to estimating the capacity available for your data is to omit the largest drive and then add
the capacity of the remaining drives. If you plan to use Dual Disk Redundancy, omit the largest two
drives. For example:
Single Disk (Default) Redundancy
Dual Disk Redundancy
Notes:
Actual capacity is often less than what is shown in the examples above due to the
different systems used for rating capacity. This has nothing to do with Drobo devices.
Know that all Drobo devices enable you to easily increase storage capacity at any
time by simply inserting additional drives or replacing smaller drives with larger
ones.
