■3.1.1. FAST (RAID 0)– Preconfigured mode of the 2big
In Fast mode, the two physical disks are striped |
|
together (RAID 0) so that one larger logical volume |
|
mounts on the desktop, offering the maximum possible |
|
capacity like in Big mode (the available capacities of |
|
each disk are cumulated) yet with greater speed than the |
|
Big mode (the speed of each disk are cumulated to a |
|
certain level). | One Fast volume |
important info: If one physical disk fails, the |
|
data of both disks become inaccessible. |
