3.1. About RAID Modes

This section will help you decide which RAID mode is right for

your application.

3.1.1. Fast (RAID 0)

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 opti-

mal playback performance. While a RAID 0 array is suited

for actively working with ﬁles (editing video, for example),

users interested in a higher level of security should use

RAID1.
