LaCie 5big Thunderbolt™ Series User Manual 16
Mirrored RAID Set (RAID 1)
In a Mirrored RAID Set, the physical disks are mirrored together so that one single logical volume mounts on the
desktop. Please note that the combined storage will not exceed the available capacity of the lowest-capacity
single disk. All data is saved simultaneously on each disk which means that files will not be lost if one drive
should fail. A Mirrored RAID set always consists for two disks. Therefore, since the LaCie 5big has five disks, you
can create two separate sets (each with two disks). A total of three volumes will then mount on your computer:
one for each of the two mirrored sets, and one single-disk (and non-mirrored) volume.
JBOD
JBOD is not technically a RAID mode, since all disks are independent, with no collective properties. Each physical
disk is mapped to a different logical volume. As a result, one volume for each disk will mount on the computer.
No protection is provided, so if a disk fails, all data contained on that disk is lost.
