 Capacity varies depend-

ing upon RAID mode.

Big, Fast and JBOD = total accessible capacity
Safe 100 (RAID 1) = 50% capacity

❖

❖

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). 

  If  one  physical  disk  fails,  the 

data of both disks become inaccessible.
