■ Spanning Mode (Enables use as a large-capacity hard drive)
In this mode, all four hard drives are combined into a large single drive with capacity equal to the sum of
the four individual drives. Because data is saved without distributing to the drives, the data access speed
is the same as that of an individual drive. Spanning mode has no mechanisms for protecting data. As a
result, failure of a single drive means that all data on the drives is lost.
