RAID 0
would create a single logical drive with a total disk capacity of
4GB.
Disk spanning is considered non-RAID due to the fact that it
neither provides redundancy nor improves performance. Disk
spanning is inexpensive, flexible, and easy to implement;
however, it does not improve the performance of the drives and
any disk failure could result to total data loss.

RAID 0
RAID 0 implements block striping where data is broken into
logical blocks and striped across several drives. Although called
RAID 0, this is not a true implementation of RAID because there
is no facility for redundancy. In the event of a disk failure, data
is lost.
In block striping, the total disk capacity is equivalent to the sum
of the capacities of all SCSI drives in the combination. This
combination of drives appears to the system as a single logical
drive.
RAID 0 provides the highest performance without redundancy.
It is fast because data can be simultaneously transferred to/from
