3.1. About RAID Modes
This section will help you decide which RAID mode is right for
your application.
Fast (RAID 0)
3.1.1.
The 2big Quadra is pre-configured in RAID 0, the fastest RAID
mode. Requiring at least 2 drives, RAID 0 stripes data onto each
disk. The available capacities of each disk are added together so
that one logical volume mounts on the computer.
If one physical disk in the array fails, the data of all disks be-
comes inaccessible because parts of the data have been written
to all disks.
Applications
RAID 0 is ideal for users who need maximum speed and
capacity. Video editors working with very large files may
use RAID 0 when editing multiple streams of video for
optimal playback performance. While a RAID 0 array is
suited for actively working with files (editing video, for ex-
ample), users interested in a higher level of security should
use RAID1.
