At this point,HAMMER seems like a RAID0
In case a HAMMER filesystem consists of mulitple disks, the capacity of 
all disks is used. That has nothing to do with striping (RAID0). Space 
can be allocated and used from each disk.

With RAID there are fixed rules on which disk a sector resides (disk 0, 
disk 1, disk 0 for striping with 2 disks for example), and there is no 
explicit information on which disk a given block resides, while HAMMER 
makes this explicit and uses AFAIK chunks of continous space.
