3.1. About RAID Modes
This section will help you decide which RAID mode is right for your
application.
3.1.1. RAID 0
The 2big Quadra Enterprise class is pre-configured in RAID 0, the
fastest RAID mode. Requiring at least 2 drives, RAID 0 stripes data
onto each disk (Fig. 07). 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 becomes
inaccessible because parts of the data have been written to all disks.
RAID Mode Capacity Protection Speed
Fast (RAID 0) 100%
Big (Concatenation) 100%
Safe (RAID 1) 50%
Mixed (RAID 0 and RAID 1) 75%
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. A RAID 0 array is more suited for
actively working with files (editing video, for example) and
should not be used as a storage backup.
