Green: Disk capacity that spans beyond the level of RAID assigned by LaCie SimplyRAID. This space is
reserved for expansion should you add new or larger capacity disks.
Storage capacity and distribution
Factors that determine available data capacity include:
The amount of disks in the enclosure
The storage capacity of each disk (see note below on mixed capacities)
RAID Mode
Single disk or double disk security
Examples:
Manual RAID 0 configuration with five disks. The only color is dark blue since RAID 0 has no protection
and all the disks are of equal capacity (2TB).
LaCie SimplyRAID configuration with five disks. All colors are represented since the RAID array uses
single disk security and the disks are of mixed capacities.
