Whats the difference between striping and spanning?
Striping and spanning are both forms of RAID 0. In a stripe RAID setup, the RAID will write a little bit of data to each drive in turn. The cool part is that it can write to all disks in the RAID at the same time. Because of this a user will see a speed increase for every drive added to the stripe. Spanning, on the other hand, will write to one disk until it is full and then begin on the next disk. Someone might choose spanning if they have hard disks of different sizes but for some reason would like to treat them as one volume.
