RAID 0, also known as striping, spreads data across multiple disks in
such a way that they can still act as one large disk. A RAID 0 virtual
disk is faster than a single disk; multiple read and write operations can
be executed in parallel on different disks in the RAID set. RAID 0 is less
reliable than a single disk, because the whole set is useless if a single disk
fails. With more disks, failures are statistically more likely to happen.
